This document details our Swift implementation and its integration with BitChat's decentralized mesh network.\n\n## The Noise Protocol Framework\n\n### Why Noise?\n\nThe Noise Protocol Framework offers:\n- **Forward Secrecy**: Past messages remain secure even if keys are compromised\n- **Identity Hiding**: Peer identities are encrypted during handshake\n- **Simplicity**: Clean, auditable protocol with minimal complexity\n- **Performance**: Efficient for resource-constrained mobile devices\n- **Flexibility**: Supports various handshake patterns\n\n### The XX Pattern\n\nBitChat uses the Noise XX pattern:\n```\nXX:\n -> e\n <- e, ee, s, es\n -> s, se\n```\n\nThis three-message pattern provides:\n- Mutual authentication\n- Identity encryption (identities revealed only after initial key exchange)\n- Resistance to key-compromise impersonation\n\n## Implementation Architecture\n\n### Core Components\n\n#### NoiseEncryptionService\nThe main service managing all Noise operations:\n```swift\nfinal class NoiseEncryptionService {\n private let staticIdentityKey: Curve25519.KeyAgreement.PrivateKey\n private let sessionManager: NoiseSessionManager\n private let channelEncryption = NoiseChannelEncryption()\n}\n```\n\n#### NoiseSession\nIndividual session state for each peer:\n```swift\nfinal class NoiseSession {\n private var handshakeState: NoiseHandshakeState?\n private var sendCipher: NoiseCipherState?\n private var receiveCipher: NoiseCipherState?\n private let remoteStaticKey: Curve25519.KeyAgreement.PublicKey?\n}\n```\n\n#### NoiseSessionManager\nThread-safe session management:\n```swift\nfinal class NoiseSessionManager {\n private var sessions: [String: NoiseSession] = [:]\n private let sessionsQueue = DispatchQueue(label: \"noise.sessions\", attributes: .concurrent)\n}\n```\n\n### Handshake Flow\n\n1. **Initiator sends ephemeral key**\n ```swift\n let ephemeralKey = Curve25519.KeyAgreement.PrivateKey()\n let message = ephemeralKey.publicKey.rawRepresentation\n ```\n\n2. **Responder sends ephemeral + encrypted static**\n ```swift\n // Generate ephemeral, perform DH, encrypt static key\n let encryptedStatic = encrypt(staticKey, using: sharedSecret)\n ```\n\n3. **Initiator sends encrypted static**\n ```swift\n // Complete handshake, derive session keys\n let (sendKey, recvKey) = deriveSessionKeys(transcript)\n ```\n\n### Session Management\n\nSessions are managed with automatic cleanup and rekey support:\n\n```swift\n// Session lookup by peer ID\nfunc getSession(for peerID: String) -> NoiseSession?\n\n// Automatic session removal on disconnect\nfunc removeSession(for peerID: String)\n\n// Rekey detection\nfunc getSessionsNeedingRekey() -> [(String, Bool)]\n```\n\n## Integration with BitChat\n\n### Peer ID Rotation\n\nNoise sessions persist across peer ID rotations through fingerprint mapping:\n\n```swift\n// Identity announcement after handshake\nstruct NoiseIdentityAnnouncement {\n let peerID: String\n let publicKey: Data\n let nickname: String\n let previousPeerID: String?\n let signature: Data\n}\n```\n\n### Message Encryption\n\nAll messages are encrypted using established Noise sessions:\n\n```swift\n// Encrypt message\nlet encrypted = try noiseService.encrypt(messageData, for: peerID)\n\n// Decrypt message \nlet decrypted = try noiseService.decrypt(encryptedData, from: peerID)\n```\n\n## Security Properties\n\n### Forward Secrecy\n- Ephemeral keys are generated for each handshake\n- Past sessions cannot be decrypted with current keys\n- Automatic rekey after 1 hour or 10,000 messages\n\n### Authentication\n- Static keys provide long-term identity\n- Handshake ensures mutual authentication\n- MAC tags prevent message tampering\n\n### Privacy\n- Peer identities encrypted during handshake\n- Metadata minimization through padding\n- No persistent session identifiers\n\n## Implementation Details\n\n### Cryptographic Primitives\n- **DH**: X25519 (Curve25519)\n- **Cipher**: ChaChaPoly (AEAD)\n- **Hash**: SHA-256\n- **KDF**: HKDF-SHA256\n\n### Error Handling\n```swift\nenum NoiseError: Error {\n case handshakeFailed\n case invalidMessage\n case sessionNotEstablished\n case decryptionFailed\n}\n```\n\n## Performance Optimizations\n\n### Connection Pooling\n- Reuse established sessions\n- Lazy handshake initiation\n- Session caching with TTL\n\n### Message Batching\n- Combine small messages\n- Reduce encryption overhead\n- Optimize for BLE MTU\n\n### Memory Management\n- Bounded session cache\n- Automatic cleanup of stale sessions\n- Efficient key rotation\n\n## Protocol Version Negotiation\n\nBitChat implements protocol version negotiation to ensure compatibility between different client versions:\n\n### Version Negotiation Flow\n1. **Version Hello**: Upon connection, peers exchange supported protocol versions\n2. **Version Agreement**: Peers agree on the highest common version\n3. **Graceful Fallback**: Legacy peers without version negotiation assume protocol v1\n\n### Message Types\n```swift\ncase versionHello = 0x20 // Announce supported versions\ncase versionAck = 0x21 // Acknowledge and agree on version\n```\n\n### Backward Compatibility\n- Peers that don't send version negotiation messages are assumed to support v1\n- Future protocol versions can be added to `ProtocolVersion.supportedVersions`\n- Incompatible peers receive a rejection message and disconnect gracefully\n\n## Future Enhancements\n\n### Post-Quantum Readiness\n- Hybrid handshake patterns\n- Kyber integration plans\n- Graceful algorithm migration\n\n### Advanced Features\n- Multi-device support\n- Session backup/restore\n- Group messaging primitives\n\n## Conclusion\n\nBitChat's Noise implementation provides encryption while maintaining the simplicity and performance required for a peer-to-peer messaging application. The protocol's elegant design ensures that people's communications remain private, authenticated, and forward-secure without sacrificing usability.\n" }, { "path": "Configs/Debug.xcconfig", "content": "#include \"Release.xcconfig\"\n\n// Optional include of local configs\n#include? \"Local.xcconfig\"\n" }, { "path": "Configs/Local.xcconfig.example", "content": "// Your Apple Developer Team ID - https://stackoverflow.com/a/18727947\nDEVELOPMENT_TEAM = ABC123\n\n// Unique bundle id to be able to register and run locally\nPRODUCT_BUNDLE_IDENTIFIER = chat.bitchat.$(DEVELOPMENT_TEAM)\n" }, { "path": "Configs/Release.xcconfig", "content": "MARKETING_VERSION = 1.5.1\nCURRENT_PROJECT_VERSION = 1\n\nIPHONEOS_DEPLOYMENT_TARGET = 16.0\nMACOSX_DEPLOYMENT_TARGET = 13.0\nSWIFT_VERSION = 5.0\n\nDEVELOPMENT_TEAM = L3N5LHJD5Y\nCODE_SIGN_STYLE = Automatic\n\nPRODUCT_BUNDLE_IDENTIFIER = chat.bitchat\n" }, { "path": "Justfile", "content": "# BitChat macOS Build Justfile\n# Handles temporary modifications needed to build and run on macOS\n\n# Default recipe - shows available commands\ndefault:\n @echo \"BitChat macOS Build Commands:\"\n @echo \" just run - Build and run the macOS app\"\n @echo \" just build - Build the macOS app only\"\n @echo \" just clean - Clean build artifacts and restore original files\"\n @echo \" just check - Check prerequisites\"\n @echo \"\"\n @echo \"Original files are preserved - modifications are temporary for builds only\"\n\n# Check prerequisites\ncheck:\n @echo \"Checking prerequisites...\"\n @command -v xcodebuild >/dev/null 2>&1 || (echo \"❌ xcodebuild not found.

This whitepaper details the BitChat Protocol Stack, a layered architecture that combines a modern cryptographic foundation with a flexible application protocol. At its core, BitChat leverages the Noise Protocol Framework (specifically, the `XX` pattern) to establish mutually authenticated, end-to-end encrypted sessions between peers. This document provides a technical specification of the identity management, session lifecycle, message framing, and security considerations that underpin the BitChat network.\n\n---\n\n## 1. Introduction\n\nIn an era of centralized communication platforms, BitChat offers a resilient alternative by operating without central servers. It is designed for scenarios where internet connectivity is unavailable or untrustworthy, such as protests, natural disasters, or remote areas. Communication occurs directly between devices over transports like Bluetooth Low Energy (BLE).\n\nThe design goals of the BitChat Protocol are:\n\n* **Confidentiality:** All communication must be unreadable to third parties.\n* **Authentication:** Users must be able to verify the identity of their correspondents.\n* **Integrity:** Messages cannot be tampered with in transit.\n* **Forward Secrecy:** The compromise of long-term identity keys must not compromise past session keys.\n* **Deniability:** It should be difficult to cryptographically prove that a specific user sent a particular message.\n* **Resilience:** The protocol must function reliably in lossy, low-bandwidth environments.\n\nThis paper specifies the technical details of the protocol designed to meet these goals.\n\n---\n\n## 2. Protocol Stack\n\nThe BitChat Protocol is a four-layer stack. This layered approach separates concerns, allowing for modularity and future extensibility.\n\n```mermaid\ngraph TD\n A[Application Layer] --> B[Session Layer];\n B --> C[Encryption Layer];\n C --> D[Transport Layer];\n\n subgraph \"BitChat Application\"\n A\n end\n\n subgraph \"Message Framing & State\"\n B\n end\n\n subgraph \"Noise Protocol Framework\"\n C\n end\n\n subgraph \"BLE, Wi-Fi Direct, etc.\"\n D\n end\n\n style A fill:#cde4ff\n style B fill:#b5d8ff\n style C fill:#9ac2ff\n style D fill:#7eadff\n```\n\n* **Application Layer:** Defines the structure of user-facing messages (`BitchatMessage`), acknowledgments (`DeliveryAck`), and other application-level data.\n* **Session Layer:** Manages the overall communication packet (`BitchatPacket`). This includes routing information (TTL), message typing, fragmentation, and serialization into a compact binary format.\n* **Encryption Layer:** Establishes and manages secure channels using the Noise Protocol Framework. It is responsible for the cryptographic handshake, session management, and transport message encryption/decryption.\n* **Transport Layer:** The underlying physical medium used for data transmission, such as Bluetooth Low Energy (BLE). This layer is abstracted away from the core protocol.\n\n---\n\n## 3. Identity and Key Management\n\nA peer's identity in BitChat is defined by two persistent cryptographic key pairs, which are generated on first launch and stored securely in the device's Keychain.\n\n1. **Noise Static Key Pair (`Curve25519`):** This is the long-term identity key used for the Noise Protocol handshake. The public part of this key is shared with peers to establish secure sessions.\n2. **Signing Key Pair (`Ed25519`):** This key is used to sign announcements and other protocol messages where non-repudiation is required, such as binding a public key to a nickname.\n\n### 3.1. Fingerprint\n\nA user's unique, verifiable fingerprint is the **SHA-256 hash** of their **Noise static public key**. This provides a user-friendly and secure way to verify an identity out-of-band (e.g., by reading it aloud or scanning a QR code).\n\n`Fingerprint = SHA256(StaticPublicKey_Curve25519)`\n\n### 3.2. Identity Management\n\nThe `SecureIdentityStateManager` class is responsible for managing all cryptographic identity material and social metadata (petnames, trust levels, etc.). It uses an in-memory cache for performance and persists this cache to the Keychain after encrypting it with a separate AES-GCM key.\n\n---\n\n## 4. The Social Trust Layer\n\nBeyond cryptographic identity, BitChat incorporates a social trust layer, allowing users to manage their relationships with peers. This functionality is handled by the `SecureIdentityStateManager`.\n\n### 4.1. Peer Verification\n\nWhile the Noise handshake cryptographically authenticates a peer's key, it doesn't confirm the real-world identity of the person holding the device. To solve this, users can perform out-of-band (OOB) verification by comparing fingerprints. Once a user confirms that a peer's fingerprint matches the one they expect, they can mark that peer as \"verified\". This status is stored locally and displayed in the UI, providing a strong assurance of identity for future conversations.\n\n### 4.2. Favorites and Blocking\n\nTo improve the user experience and provide control over interactions, the protocol supports:\n* **Favorites:** Users can mark trusted or frequently contacted peers as \"favorites\". This is a local designation that can be used by the application to prioritize notifications or display peers more prominently.\n* **Blocking:** Users can block peers. When a peer is blocked, the application will discard any incoming packets from that peer's fingerprint at the earliest possible stage, effectively silencing them without notifying the blocked peer.\n\n---\n\n## 5. The Noise Protocol Layer\n\nBitChat implements the Noise Protocol Framework to provide strong, authenticated end-to-end encryption.\n\n### 5.1. Protocol Name\n\nThe specific Noise protocol implemented is:\n\n**`Noise_XX_25519_ChaChaPoly_SHA256`**\n\n* **`XX` Pattern:** This handshake pattern provides mutual authentication and forward secrecy. It does not require either party to know the other's static public key before the handshake begins. The keys are exchanged and authenticated during the three-part handshake. This is ideal for a decentralized P2P environment.\n* **`25519`:** The Diffie-Hellman function used is Curve25519.\n* **`ChaChaPoly`:** The AEAD (Authenticated Encryption with Associated Data) cipher is ChaCha20-Poly1305.\n* **`SHA256`:** The hash function used for all cryptographic hashing operations is SHA-256.\n\n### 5.2. The `XX` Handshake\n\nThe `XX` handshake consists of three messages exchanged between an Initiator and a Responder to establish a shared secret and derive transport encryption keys.\n\n```mermaid\nsequenceDiagram\n participant I as Initiator\n participant R as Responder\n\n Note over I, R: Pre-computation: h = SHA256(protocol_name)\n\n I->>R: -> e\n Note right of I: I generates ephemeral key `e_i`.
h = SHA256(h + e_i.pub)\n\n R->>I: <- e, ee, s, es\n Note left of R: R generates ephemeral key `e_r`.
h = SHA256(h + e_r.pub)
MixKey(DH(e_i, e_r))
R sends static key `s_r`, encrypted.
h = SHA256(h + ciphertext)
MixKey(DH(e_i, s_r))\n\n I->>R: -> s, se\n Note right of I: I decrypts and verifies `s_r`.
I sends static key `s_i`, encrypted.
h = SHA256(h + ciphertext)
MixKey(DH(s_i, e_r))\n\n Note over I, R: Handshake complete. Transport keys derived.\n```\n\n**Handshake Flow:**\n\n1. **Initiator -> Responder:** The initiator generates a new ephemeral key pair (`e_i`) and sends the public part to the responder.\n2. **Responder -> Initiator:** The responder receives the initiator's ephemeral public key. It then generates its own ephemeral key pair (`e_r`), performs a DH exchange with the initiator's ephemeral key (`ee`), sends its own static public key (`s_r`) encrypted with the resulting symmetric key, and performs another DH exchange between the initiator's ephemeral key and its own static key (`es`).\n3. **Initiator -> Responder:** The initiator receives the responder's message, decrypts the responder's static key, and authenticates it. The initiator then sends its own static key (`s_i`) encrypted and performs a final DH exchange between its static key and the responder's ephemeral key (`se`).\n\nUpon completion, both parties share a set of symmetric keys for bidirectional transport message encryption. The final handshake hash is used for channel binding.\n\n### 5.3. Session Management\n\nThe `NoiseSessionManager` class manages all active Noise sessions. It handles:\n* Creating sessions for new peers.\n* Coordinating the handshake process to prevent race conditions.\n* Storing the resulting transport ciphers (`sendCipher`, `receiveCipher`).\n* Periodically checking if sessions need to be re-keyed for enhanced security.\n\n---\n\n## 6. The BitChat Session and Application Protocol\n\nOnce a Noise session is established, peers exchange `BitchatPacket` structures, which are encrypted as the payload of Noise transport messages.\n\n### 6.1. Binary Packet Format (`BitchatPacket`)\n\nTo minimize bandwidth, `BitchatPacket`s are serialized into a compact binary format. The structure is designed to be fixed-size where possible to resist traffic analysis.\n\n| Field | Size (bytes) | Description |\n|-----------------|--------------|---------------------------------------------------------------------------------------------------------|\n| **Header** | **13** | **Fixed-size header** |\n| Version | 1 | Protocol version (currently `1`). |\n| Type | 1 | Message type (e.g., `message`, `deliveryAck`, `noiseHandshakeInit`).

Present if `hasSignature` flag is set. |\n\n**Padding:** All packets are padded to the next standard block size (256, 512, 1024, or 2048 bytes) using a PKCS#7-style scheme to obscure the true message length from network observers.\n\n```mermaid\n---\nconfig:\n theme: dark\n---\n---\ntitle: \"BitchatPacket\"\n---\npacket\n+8: \"Version\"\n+8: \"Type\"\n+8: \"TTL\"\n+64: \"Timestamp\"\n+8: \"Flags\"\n+16: \"Payload Length\"\n+64: \"Sender ID\"\n+64: \"Recipient ID (optional)\"\n+48: \"Payload (variable)\"\n+64: \"Signature (optional)\"\n```\n_A representation of the sizes of the fields in `BitchatPacket`_\n\n### 6.2.

Message Routing and Propagation\n\nBitChat operates as a decentralized mesh network, meaning there are no central servers to route messages. Packets are propagated through the network from peer to peer. The protocol supports several modes of message delivery.\n\n### 7.1. Direct Connection\n\nThis is the simplest case. If Peer A and Peer B are directly connected, they can exchange packets after establishing a mutually authenticated Noise session. All packets are encrypted using the transport ciphers derived from the handshake.\n\n### 7.2. Efficient Gossip with Bloom Filters\n\nTo send messages to peers that are not directly connected, BitChat employs a \"flooding\" or \"gossip\" protocol. When a peer receives a packet that is not destined for it, it acts as a relay. To prevent infinite routing loops and minimize memory usage, the protocol uses an `OptimizedBloomFilter` to track recently seen packet IDs.\n\nThe logic is as follows:\n\n1. A peer receives a packet.\n2. It checks the Bloom filter to see if the packet's ID has likely been seen before. If so, the packet is discarded. Bloom filters can have false positives (though they are rare), but they guarantee no false negatives. This means that while some packets may be incorrectly discarded due to false positives, the gossip protocol's redundancy ensures these packets will eventually be received through subsequent exchanges with other peers.\n3. If the packet is new, its ID is added to the Bloom filter.\n4. The peer decrements the packet's Time-To-Live (TTL) field.\n5. If the TTL is greater than zero, the peer re-broadcasts the packet to all of its connected peers, *except* for the peer from which it received the packet.\n\nThis mechanism allows packets to \"flood\" through the network efficiently, maximizing the chance of reaching their destination while using minimal resources to prevent loops.\n\n### 7.3. Time-To-Live (TTL)\n\nEvery `BitchatPacket` contains an 8-bit TTL field. This value is set by the originating peer and is decremented by one at each relay hop. If a peer receives a packet and decrements its TTL to 0, it will process the packet (if it is the recipient) but will not relay it further. This is a crucial mechanism to prevent packets from circulating endlessly in the mesh.\n\n### 7.4. Private vs. Broadcast Messages\n\nThe routing logic respects the confidentiality of private messages:\n\n* **Private Messages:** A packet with a specific `recipientID` is a private message. Relay nodes forward the entire, encrypted Noise message without being able to access the inner `BitchatPacket` or its payload. Only the final recipient, who shares the correct Noise session keys with the sender, can decrypt the packet.\n* **Broadcast Messages:** A packet with the special broadcast `recipientID` (`0xFFFFFFFFFFFFFFFF`) is intended for all peers. Any peer that receives and decrypts a broadcast message will process its content. It will still be relayed according to the flooding algorithm to ensure it reaches the entire network.\n\n### 7.5. Message Reliability and Lifecycle\n\nTo function in unreliable, lossy networks, the protocol includes features to track the lifecycle of a message and ensure its delivery.\n\n* **Delivery Acknowledgments (`DeliveryAck`):** When a private message reaches its final destination, the recipient's device sends a `DeliveryAck` packet back to the original sender. This acknowledgment contains the ID of the original message.\n* **Read Receipts (`ReadReceipt`):** After a message is displayed on the recipient's screen, the application can send a `ReadReceipt`, also containing the original message ID, to inform the sender that the message has been seen.\n* **Message Retry Service:** Senders maintain a `MessageRetryService` which tracks outgoing messages. If a `DeliveryAck` is not received for a message within a certain time window, the service will automatically re-send the message, creating a more resilient user experience.\n\n### 7.6. Fragmentation\n\nTransport layers like BLE have a Maximum Transmission Unit (MTU) that limits the size of a single packet. To handle messages larger than this limit, BitChat implements a fragmentation protocol.\n\n* **`fragmentStart`:** A packet with this type marks the beginning of a fragmented message. It contains metadata about the total size and number of fragments.\n* **`fragmentContinue`:** These packets carry the intermediate chunks of the message data.\n* **`fragmentEnd`:** This packet carries the final chunk of the message and signals the receiver to begin reassembly.\n\nReceiving peers collect all fragments and reassemble them in the correct order before passing the complete message up to the application layer.\n\n---\n\n## 8. Security Considerations\n\n* **Replay Attacks:** The Noise transport messages include a nonce that is incremented for each message. The `NoiseCipherState` implements a sliding window replay protection mechanism to detect and discard replayed or out-of-order messages.\n* **Denial of Service:** The `NoiseRateLimiter` is implemented to prevent resource exhaustion from rapid, repeated handshake attempts from a single peer.\n* **Key-Compromise Impersonation:** The `XX` pattern authenticates both parties, preventing an attacker from impersonating one party to the other.\n* **Identity Binding:** While the Noise handshake authenticates the cryptographic keys, binding those keys to a human-readable nickname is handled at the application layer. Users must verify fingerprints out-of-band to prevent man-in-the-middle attacks.\n* **Traffic Analysis:** The use of fixed-size padding for all packets helps to obscure the exact nature and content of the communication, making it harder for a network-level adversary to infer information based on message size.\n\n---\n\n## 9. Conclusion\n\nThe BitChat Protocol provides a robust and secure foundation for decentralized, peer-to-peer communication. By layering a flexible application protocol on top of the well-regarded Noise Protocol Framework, it achieves strong confidentiality, authentication, and forward secrecy.

Identity cache encrypted with AES-GCM\n/// - Unique 256-bit encryption key per device\n/// - Key stored separately in Keychain\n/// - No plaintext identity data on disk\n///\n/// ### Privacy by Design\n/// - Persistence is optional (user-controlled)\n/// - Minimal data retention\n/// - No cloud sync or backup\n/// - Automatic cleanup of stale entries\n///\n/// ### Thread Safety\n/// - Concurrent read access via GCD barriers\n/// - Write operations serialized\n/// - Atomic state updates\n/// - No data races or corruption\n///\n/// ## Data Model\n/// Manages three types of identity data:\n/// 1. **Ephemeral Sessions**: Current peer connections\n/// 2. **Cryptographic Identities**: Public keys and fingerprints\n/// 3. **Social Identities**: User-assigned names and trust\n///\n/// ## Persistence Strategy\n/// - Changes batched and debounced (2-second window)\n/// - Automatic save on app termination\n/// - Crash-resistant with atomic writes\n/// - Migration support for schema changes\n///\n/// ## Usage Patterns\n/// ```swift\n/// // Register a new peer identity\n/// manager.registerPeerIdentity(peerID, publicKey, fingerprint)\n/// \n/// // Update social identity\n/// manager.updateSocialIdentity(fingerprint, nickname, trustLevel)\n/// \n/// // Query identity\n/// let identity = manager.resolvePeerIdentity(peerID)\n/// ```\n///\n/// ## Performance Optimizations\n/// - In-memory cache eliminates Keychain roundtrips\n/// - Debounced saves reduce I/O operations\n/// - Efficient data structures for lookups\n/// - Background queue for expensive operations\n///\n/// ## Privacy Considerations\n/// - Users can disable all persistence\n/// - Identity cache can be wiped instantly\n/// - No analytics or telemetry\n/// - Ephemeral mode for high-risk users\n///\n/// ## Future Enhancements\n/// - Selective identity export\n/// - Cross-device identity sync (optional)\n/// - Identity attestation support\n/// - Advanced conflict resolution\n///\n\nimport BitLogger\nimport Foundation\nimport CryptoKit\n\nprotocol SecureIdentityStateManagerProtocol {\n // MARK: Secure Loading/Saving\n func forceSave()\n \n // MARK: Social Identity Management\n func getSocialIdentity(for fingerprint: String) -> SocialIdentity?\n \n // MARK: Cryptographic Identities\n func upsertCryptographicIdentity(fingerprint: String, noisePublicKey: Data, signingPublicKey: Data?, claimedNickname: String?)\n func getCryptoIdentitiesByPeerIDPrefix(_ peerID: PeerID) -> [CryptographicIdentity]\n func updateSocialIdentity(_ identity: SocialIdentity)\n \n // MARK: Favorites Management\n func getFavorites() -> Set\n func setFavorite(_ fingerprint: String, isFavorite: Bool)\n func isFavorite(fingerprint: String) -> Bool\n \n // MARK: Blocked Users Management\n func isBlocked(fingerprint: String) -> Bool\n func setBlocked(_ fingerprint: String, isBlocked: Bool)\n \n // MARK: Geohash (Nostr) Blocking\n func isNostrBlocked(pubkeyHexLowercased: String) -> Bool\n func setNostrBlocked(_ pubkeyHexLowercased: String, isBlocked: Bool)\n func getBlockedNostrPubkeys() -> Set\n \n // MARK: Ephemeral Session Management\n func registerEphemeralSession(peerID: PeerID, handshakeState: HandshakeState)\n func updateHandshakeState(peerID: PeerID, state: HandshakeState)\n \n // MARK: Cleanup\n func clearAllIdentityData()\n func removeEphemeralSession(peerID: PeerID)\n \n // MARK: Verification\n func setVerified(fingerprint: String, verified: Bool)\n func isVerified(fingerprint: String) -> Bool\n func getVerifiedFingerprints() -> Set\n}\n\n/// Singleton manager for secure identity state persistence and retrieval.\n/// Provides thread-safe access to identity mappings with encryption at rest.\n/// All identity data is stored encrypted in the device Keychain for security.\nfinal class SecureIdentityStateManager: SecureIdentityStateManagerProtocol {\n private let keychain: KeychainManagerProtocol\n private let cacheKey = \"bitchat.identityCache.v2\"\n private let encryptionKeyName = \"identityCacheEncryptionKey\"\n \n // In-memory state\n private var ephemeralSessions: [PeerID: EphemeralIdentity] = [:]\n private var cryptographicIdentities: [String: CryptographicIdentity] = [:]\n private var cache: IdentityCache = IdentityCache()\n \n // Thread safety\n private let queue = DispatchQueue(label: \"bitchat.identity.state\", attributes: .concurrent)\n \n // Debouncing for keychain saves\n private var saveTimer: Timer?\n private let saveDebounceInterval: TimeInterval = 2.0 // Save at most once every 2 seconds\n private var pendingSave = false\n \n // Encryption key\n private let encryptionKey: SymmetricKey\n \n init(_ keychain: KeychainManagerProtocol) {\n self.keychain = keychain\n \n // Generate or retrieve encryption key from keychain\n let loadedKey: SymmetricKey\n \n // Try to load from keychain\n if let keyData = keychain.getIdentityKey(forKey: encryptionKeyName) {\n loadedKey = SymmetricKey(data: keyData)\n SecureLogger.logKeyOperation(.load, keyType: \"identity cache encryption key\", success: true)\n }\n // Generate new key if needed\n else {\n loadedKey = SymmetricKey(size: .bits256)\n let keyData = loadedKey.withUnsafeBytes { Data($0) }\n // Save to keychain\n let saved = keychain.saveIdentityKey(keyData, forKey: encryptionKeyName)\n SecureLogger.logKeyOperation(.generate, keyType: \"identity cache encryption key\", success: saved)\n }\n \n self.encryptionKey = loadedKey\n \n // Load identity cache on init\n loadIdentityCache()\n }\n \n deinit {\n forceSave()\n }\n \n // MARK: -

This file contains the core cryptographic primitives\n/// and handshake logic that enable secure communication between peers.\n///\n/// ## Overview\n/// The Noise Protocol Framework is a modern cryptographic framework designed\n/// for building secure protocols. BitChat uses Noise to provide:\n/// - Mutual authentication between peers\n/// - Forward secrecy for all messages\n/// - Protection against replay attacks\n/// - Minimal round trips for connection establishment\n///\n/// ## Implementation Details\n/// This implementation follows the Noise specification exactly, using:\n/// - **Pattern**: XX (most versatile, provides mutual authentication)\n/// - **DH**: Curve25519 (X25519 key exchange)\n/// - **Cipher**: ChaCha20-Poly1305 (AEAD encryption)\n/// - **Hash**: SHA-256 (for key derivation and authentication)\n///\n/// ## Security Properties\n/// The XX handshake pattern provides:\n/// 1. **Identity Hiding**: Both parties' identities are encrypted\n/// 2. **Forward Secrecy**: Past sessions remain secure if keys are compromised\n/// 3. **Key Compromise Impersonation Resistance**: Compromised static key doesn't allow impersonation to that party\n/// 4. **Mutual Authentication**: Both parties verify each other's identity\n///\n/// ## Handshake Flow (XX Pattern)\n/// ```\n/// Initiator Responder\n/// --------- ---------\n/// -> e (ephemeral key)\n/// <- e, ee, s, es (ephemeral, DH, static encrypted, DH)\n/// -> s, se (static encrypted, DH)\n/// ```\n///\n/// ## Key Components\n/// - **NoiseCipherState**: Manages symmetric encryption with nonce tracking\n/// - **NoiseSymmetricState**: Handles key derivation and handshake hashing\n/// - **NoiseHandshakeState**: Orchestrates the complete handshake process\n///\n/// ## Replay Protection\n/// Implements sliding window replay protection to prevent message replay attacks:\n/// - Tracks nonces within a 1024-message window\n/// - Rejects duplicate or too-old nonces\n/// - Handles out-of-order message delivery\n///\n/// ## Usage Example\n/// ```swift\n/// let handshake = NoiseHandshakeState(\n/// pattern: .XX,\n/// role: .initiator,\n/// localStatic: staticKeyPair\n/// )\n/// let messageBuffer = handshake.writeMessage(payload: Data())\n/// // Send messageBuffer to peer...\n/// ```\n///\n/// ## Security Considerations\n/// - Static keys must be generated using secure random sources\n/// - Keys should be stored securely (e.g., in Keychain)\n/// - Handshake state must not be reused after completion\n/// - Transport messages have a nonce limit (2^64-1)\n///\n/// ## References\n/// -

It provides:\n/// - Efficient binary message encoding\n/// - Message fragmentation for large payloads\n/// - TTL-based routing for mesh networks\n/// - Privacy features like padding and timing obfuscation\n/// - Integration points for end-to-end encryption\n///\n/// ## Protocol Design\n/// The protocol uses a compact binary format to minimize overhead:\n/// - 1-byte message type identifier\n/// - Variable-length fields with length prefixes\n/// - Network byte order (big-endian) for multi-byte values\n/// - PKCS#7-style padding for privacy\n///\n/// ## Message Flow\n/// 1. **Creation**: Messages are created with type, content, and metadata\n/// 2. **Encoding**: Converted to binary format with proper field ordering\n/// 3. **Fragmentation**: Split if larger than BLE MTU (512 bytes)\n/// 4. **Transmission**: Sent via BLEService\n/// 5. **Routing**: Relayed by intermediate nodes (TTL decrements)\n/// 6. **Reassembly**: Fragments collected and reassembled\n/// 7. **Decoding**: Binary data parsed back to message objects\n///\n/// ## Security Considerations\n/// - Message padding obscures actual content length\n/// - Timing obfuscation prevents traffic analysis\n/// - Integration with Noise Protocol for E2E encryption\n/// - No persistent identifiers in protocol headers\n///\n/// ## Message Types\n/// - **Announce/Leave**: Peer presence notifications\n/// - **Message**: User chat messages (broadcast or directed)\n/// - **Fragment**: Multi-part message handling\n/// - **Delivery/Read**: Message acknowledgments\n/// - **Noise**: Encrypted channel establishment\n/// - **Version**: Protocol version negotiation\n///\n/// ## Future Extensions\n/// The protocol is designed to be extensible:\n/// - Reserved message type ranges for future use\n/// - Version field for protocol evolution\n/// - Optional fields for new features\n///\n\nimport Foundation\nimport CoreBluetooth\n\n// MARK: - Message Types\n\n/// Simplified BitChat protocol message types.\n/// Reduced from 24 types to just 6 essential ones.\n/// All private communication metadata (receipts, status) is embedded in noiseEncrypted payloads.\nenum MessageType: UInt8 {\n // Public messages (unencrypted)\n case announce = 0x01 // \"I'm here\" with nickname\n case message = 0x02 // Public chat message \n case leave = 0x03 // \"I'm leaving\"\n case requestSync = 0x21 // GCS filter-based sync request (local-only)\n \n // Noise encryption\n case noiseHandshake = 0x10 // Handshake (init or response determined by payload)\n case noiseEncrypted = 0x11 // All encrypted payloads (messages, receipts, etc.)\n \n // Fragmentation (simplified)\n case fragment = 0x20 // Single fragment type for large messages\n case fileTransfer = 0x22 // Binary file/audio/image payloads\n \n var description: String {\n switch self {\n case .announce: return \"announce\"\n case .message: return \"message\"\n case .leave: return \"leave\"\n case .requestSync: return \"requestSync\"\n case .noiseHandshake: return \"noiseHandshake\"\n case .noiseEncrypted: return \"noiseEncrypted\"\n case .fragment: return \"fragment\"\n case .fileTransfer: return \"fileTransfer\"\n }\n }\n}\n\n// MARK: -

Acts as the bridge between the transport\n/// layer (BLEService) and the cryptographic layer (NoiseProtocol).\n///\n/// ## Overview\n/// This service provides a simplified API for establishing and managing encrypted\n/// channels between peers. It handles:\n/// - Static identity key management\n/// - Session lifecycle (creation, maintenance, teardown)\n/// - Message encryption/decryption\n/// - Peer authentication and fingerprint tracking\n/// - Automatic rekeying for forward secrecy\n///\n/// ## Architecture\n/// The service operates at multiple levels:\n/// 1. **Identity Management**: Persistent Curve25519 keys stored in Keychain\n/// 2. **Session Management**: Per-peer Noise sessions with state tracking\n/// 3. **Message Processing**: Encryption/decryption with proper framing\n/// 4. **Security Features**: Rate limiting, fingerprint verification\n///\n/// ## Key Features\n///\n/// ### Identity Keys\n/// - Static Curve25519 key pair for Noise XX pattern\n/// - Ed25519 signing key pair for additional authentication\n/// - Keys persisted securely in iOS/macOS Keychain\n/// - Fingerprints derived from SHA256 of public keys\n///\n/// ### Session Management\n/// - Lazy session creation (on-demand when sending messages)\n/// - Automatic session recovery after disconnections\n/// - Configurable rekey intervals for forward secrecy\n/// - Graceful handling of simultaneous handshakes\n///\n/// ### Security Properties\n/// - Forward secrecy via ephemeral keys in handshakes\n/// - Mutual authentication via static key exchange\n/// - Protection against replay attacks\n/// - Rate limiting to prevent DoS attacks\n///\n/// ## Encryption Flow\n/// ```\n/// 1. Message arrives for encryption\n/// 2. Check if session exists for peer\n/// 3. If not, initiate Noise handshake\n/// 4. Once established, encrypt message\n/// 5. Add message type header for protocol handling\n/// 6. Return encrypted payload for transmission\n/// ```\n///\n/// ## Integration Points\n/// - **BLEService**: Calls this service for all private messages\n/// - **ChatViewModel**: Monitors encryption status for UI indicators\n/// - **KeychainManager**: Secure storage for identity keys\n///\n/// ## Thread Safety\n/// - Concurrent read access via reader-writer queue\n/// - Session operations protected by per-peer queues\n/// - Atomic updates for critical state changes\n///\n/// ## Error Handling\n/// - Graceful fallback for encryption failures\n/// - Clear error messages for debugging\n/// - Automatic retry with exponential backoff\n/// - User notification for critical failures\n///\n/// ## Performance Considerations\n/// - Sessions cached in memory for fast access\n/// - Minimal allocations in hot paths\n/// - Efficient binary message format\n/// - Background queue for CPU-intensive operations\n///\n\nimport BitLogger\nimport Foundation\nimport CryptoKit\n\n// MARK: - Encryption Status\n\n/// Represents the current encryption status of a peer connection.\n/// Used for UI indicators and decision-making about message handling.\nenum EncryptionStatus: Equatable {\n case none // Failed or incompatible\n case noHandshake // No handshake attempted yet\n case noiseHandshaking // Currently establishing\n case noiseSecured // Established but not verified\n case noiseVerified // Established and verified\n \n var icon: String?

It manages:\n/// - Message state and delivery\n/// - Peer connections and presence\n/// - Private chat sessions\n/// - Command processing\n/// - UI state like autocomplete and notifications\n///\n/// ## Architecture\n/// The ViewModel acts as:\n/// - **BitchatDelegate**: Receives messages and events from BLEService\n/// - **State Manager**: Maintains all UI-relevant state with @Published properties\n/// - **Command Processor**: Handles IRC-style commands (/msg, /who, etc.)\n/// - **Message Router**: Directs messages to appropriate chats (public/private)\n///\n/// ## Key Features\n///\n/// ### Message Management\n/// - Efficient message handling with duplicate detection\n/// - Maintains separate public and private message queues\n/// - Limits message history to prevent memory issues (1337 messages)\n/// - Tracks delivery and read receipts\n///\n/// ### Privacy Features\n/// - Ephemeral by design - no persistent message storage\n/// - Supports verified fingerprints for secure communication\n/// - Blocks messages from blocked users\n/// - Emergency wipe capability (triple-tap)\n///\n/// ### User Experience\n/// - Smart autocomplete for mentions and commands\n/// - Unread message indicators\n/// - Connection status tracking\n/// - Favorite peers management\n///\n/// ## Command System\n/// Supports IRC-style commands:\n/// - `/nick `: Change nickname\n/// - `/msg `: Send private message\n/// - `/who`: List connected peers\n/// - `/slap `: Fun interaction\n/// - `/clear`: Clear message history\n/// - `/help`: Show available commands\n///\n/// ## Performance Optimizations\n/// - SwiftUI automatically optimizes UI updates\n/// - Caches expensive computations (encryption status)\n/// - Debounces autocomplete suggestions\n/// - Efficient peer list management\n///\n/// ## Thread Safety\n/// - All @Published properties trigger UI updates on main thread\n/// - Background operations use proper queue management\n/// - Atomic operations for critical state updates\n///\n/// ## Usage Example\n/// ```swift\n/// let viewModel = ChatViewModel()\n/// viewModel.nickname = \"Alice\"\n/// viewModel.startServices()\n/// viewModel.sendMessage(\"Hello, mesh network!\")\n/// ```\n///\n\nimport BitLogger\nimport Foundation\nimport SwiftUI\nimport Combine\nimport CommonCrypto\nimport CoreBluetooth\nimport Tor\n#if os(iOS)\nimport UIKit\n#endif\nimport UniformTypeIdentifiers\n\n/// Manages the application state and business logic for BitChat.\n/// Acts as the primary coordinator between UI components and backend services,\n/// implementing the BitchatDelegate protocol to handle network events.\nfinal class ChatViewModel: ObservableObject, BitchatDelegate, CommandContextProvider, GeohashParticipantContext, MessageFormattingContext {\n // Use MessageFormattingEngine.Patterns for regex matching (shared, precompiled)\n typealias Patterns = MessageFormattingEngine.Patterns\n\n typealias GeoOutgoingContext = (channel: GeohashChannel, event: NostrEvent, identity: NostrIdentity, teleported: Bool)\n\n @MainActor\n var canSendMediaInCurrentContext: Bool {\n if let peer = selectedPrivateChatPeer {\n return !(peer.isGeoDM || peer.isGeoChat)\n }\n switch activeChannel {\n case .mesh: return true\n case .location: return false\n }\n }\n\n private var publicRateLimiter = MessageRateLimiter(\n senderCapacity: TransportConfig.uiSenderRateBucketCapacity,\n senderRefillPerSec: TransportConfig.uiSenderRateBucketRefillPerSec,\n contentCapacity: TransportConfig.uiContentRateBucketCapacity,\n contentRefillPerSec: TransportConfig.uiContentRateBucketRefillPerSec\n )\n\n @MainActor\n private func normalizedSenderKey(for message: BitchatMessage) -> String {\n if let spid = message.senderPeerID {\n if spid.isGeoChat || spid.isGeoDM {\n let full = (nostrKeyMapping[spid] ??

make end-to-end and integration tests deterministic, fast, and race-free without touching production code.\n\n## In-Memory Bus\n\n- **File:** `bitchatTests/Mocks/MockBLEService.swift`\n- **Registry/Adjacency:** Global `registry` maps `peerID` to a `MockBLEService` instance; `adjacency` records simulated links between peers.\n- **Setup:** Call `MockBLEService.resetTestBus()` in `setUp()` to clear state between tests.\n- **Topology:** Use `simulateConnectedPeer(_:)` and `simulateDisconnectedPeer(_:)` to add/remove links. `connectFullMesh()` helpers in tests build larger topologies.\n- **Handlers:** Tests can observe data via `messageDeliveryHandler` (decoded `BitchatMessage`) and `packetDeliveryHandler` (raw `BitchatPacket`).\n- **De‑duplication:** A thread-safe `seenMessageIDs` prevents duplicate deliveries during flooding/relays.\n\n## Broadcast Flooding\n\n- **Flag:** `MockBLEService.autoFloodEnabled`\n- **Intent:** When `true`, public broadcasts propagate across the entire connected component (ignores TTL for reach) while still de‑duping to prevent loops.\n- **Usage:** Enabled in Integration tests (`setUp`) to simulate large-network broadcast; disabled in E2E tests to keep routing explicit and verify TTL behavior (see `PublicChatE2ETests.testZeroTTLNotRelayed`).\n\n## Rehandshake Flow (Noise)\n\n- **Why:** The legacy NACK recovery path was removed; recovery now relies on Noise session rehandshake after decrypt failure or desync.\n- **Manager:** `NoiseSessionManager` manages per-peer sessions.\n- **Pattern:** On decrypt failure, proactively clear the local session and re-initiate a handshake. The peer accepts and replaces their session.\n- **Test:** `IntegrationTests.testRehandshakeAfterDecryptionFailure`\n - Corrupts ciphertext to induce a decrypt error.\n - Calls `removeSession(for:)` on the initiator’s manager before `initiateHandshake(with:)` to avoid `alreadyEstablished`.\n - Verifies encrypt/decrypt succeeds post-rehandshake.\n\n## Tips\n\n- **Determinism:** Add small async delays only where handler installation/topology changes could race the first send.\n- **Scoping:** Keep `autoFloodEnabled` toggled only within Integration tests; always reset in `tearDown()` to avoid cross-test contamination.\n- **Direct vs Relay:** Private messages target a specific peer when adjacent; otherwise they are surfaced to neighbors for relay and, if known, also delivered to the target.\n\n## Quick Start\n\n- Create nodes and connect them:\n - `let svc = MockBLEService(); svc.myPeerID = \"PEER1\"`\n - `svc.simulateConnectedPeer(\"PEER2\")`\n- Observe messages:\n - `svc.messageDeliveryHandler = { msg in /* asserts */ }`\n- Enable broadcast flooding for Integration suites only:\n - `MockBLEService.autoFloodEnabled = true`\n\n" }, { "path":

mechanism to track online participants in geohash-based location channels. It uses a dedicated ephemeral Nostr event kind to broadcast \"heartbeats,\" ensuring accurate and privacy-preserving online counts.\n\n## Nostr Protocol\n\n### Event Kind\nA new ephemeral event kind is defined for presence heartbeats:\n- **Kind:** `20001` (`GEOHASH_PRESENCE`)\n- **Type:** Ephemeral (not stored by relays long-term)\n\n### Event Structure\nThe presence event mimics the structure of a geohash chat message (Kind 20000) but without content or nickname metadata, to minimize overhead and focus purely on \"liveness\".\n\n```json\n{\n \"kind\": 20001,\n \"created_at\": ,\n \"tags\": [\n [\"g\", \"\"]\n ],\n \"content\": \"\",\n \"pubkey\": \"\",\n \"id\": \"\",\n \"sig\": \"\"\n}\n```\n\n* **`content`**: Must be empty string.\n* **`tags`**: Must include `[\"g\", \"\"]`. Should NOT include `[\"n\", \"\"]`.\n* **`pubkey`**: The ephemeral identity derived specifically for this geohash (same as used for chat messages).\n\n## Client Behavior\n\n### 1. Broadcasting Presence\n\nClients MUST broadcast a Kind 20001 presence event globally when the app is open, regardless of which screen the user is viewing.\n\n* **Global Heartbeat:**\n * **Trigger:** Application start / initialization, or whenever location (available geohashes) changes.\n * **Frequency:** Randomized loop interval between **40s and 80s** (average 60s).\n * **Scope:** Sent to *all* geohash channels corresponding to the device's *current physical location*.\n * **Privacy Restriction:** Presence MUST ONLY be broadcast to low-precision geohash levels to protect user privacy. Specifically:\n * **Allowed:** `REGION` (precision 2), `PROVINCE` (precision 4), `CITY` (precision 5).\n * **Denied:** `NEIGHBORHOOD` (precision 6), `BLOCK` (precision 7), `BUILDING` (precision 8+).\n * **Decorrelation:** Individual broadcasts within a heartbeat loop must be separated by random delays (e.g., 2-5 seconds) to prevent temporal correlation of public keys across different geohash levels. The main loop delay is adjusted to maintain the target average cadence.\n\n### 2. Subscribing to Presence\n\nClients must update their Nostr filters to listen for both chat and presence events on geohash channels.\n\n* **Filter:**\n * `kinds`: `[20000, 20001]`\n * `#g`: `[\"\"]`\n\n### 3. Participant Counting\n\nThe \"online participants\" count shown in the UI aggregates unique public keys from both presence heartbeats and active chat messages.\n\n* **Logic:**\n * Maintain a map of `pubkey -> last_seen_timestamp` for each geohash.\n * Update `last_seen_timestamp` upon receiving a valid **Kind 20001 (Presence)** OR **Kind 20000 (Chat)** event.\n * A participant is considered \"online\" if their `last_seen_timestamp` is within the last **5 minutes**.\n\n### 4. UI Presentation\n\nThe presentation of the participant count depends on the geohash precision level and data availability.\n\n* **Standard Display:** For channels where presence is broadcast (Region, Province, City) OR any channel where at least one participant has been detected, show the exact count: `[N people]`.\n* **High-Precision Uncertainty:** For high-precision channels (Neighborhood, Block, Building) where:\n * Presence broadcasting is disabled (privacy restriction).\n * **AND** the detected participant count is `0`.\n * **Display:** `[? people]`\n * **Reasoning:** Since clients don't announce themselves in these channels, a count of \"0\" is misleading (people could be lurking).\n\n### 5. Implementation Details (Android Reference)\n\n* **`NostrKind.GEOHASH_PRESENCE`**: Added constant `20001`.\n* **`NostrProtocol.createGeohashPresenceEvent`**: Helper to generate the event.\n* **`GeohashViewModel`**:\n * `startGlobalPresenceHeartbeat()`: Coroutine that `collectLatest` on `LocationChannelManager.availableChannels`.\n * Implements randomized loop logic (40-80s) and per-broadcast random delays (2-5s).\n * Filters channels by `precision <= 5` before broadcasting.\n* **`GeohashMessageHandler`**:\n * Refactored `onEvent` to update participant counts for both Kind 20000 and 20001.\n* **`LocationChannelsSheet`**:\n * Implements the `[? people]` display logic for high-precision, zero-count channels.\n\n## Benefits\n\n* **Accuracy:** Counts reflect both active listeners (via heartbeats) and active speakers (via messages).\n* **Privacy:** High-precision location presence is NOT broadcast. Temporal correlation between different levels is obfuscated via random delays.\n* **Consistency:** \"Online\" status is maintained globally while the app is open.\n* **Transparency:** The UI correctly reflects uncertainty (`?`) when privacy rules prevent accurate passive counting.\n" }, { "path": "docs/REQUEST_SYNC_MANAGER.md", "content": "# Request Sync Manager & V2 Packet Updates\n\nThis document details the implementation of the Request Sync Manager and updates to the V2 packet structure to improve synchronization security and attribution on iOS, mirroring the Android implementation.\n\n## Overview\n\nThe goal of these changes is to make the request sync functionality \"less blind\". Previously, sync requests were broadcast, and responses were accepted without strict attribution or timestamp validation (to allow syncing old messages). This opened up potential spoofing vectors and prevented us from enforcing timestamp checks on normal traffic.\n\nThe new implementation introduces a **RequestSyncManager** to track outgoing sync requests and attributes incoming responses (RSR - Request-Sync Response) to specific peers. This allows us to:\n1. **Enforce Timestamp Validation**: Normal packets now require timestamps to be within 2 minutes of the local clock.\n2. **Exempt Solicited Sync Responses**: Packets marked as RSR are exempt from timestamp validation *only if* they correspond to a valid, pending sync request sent to that specific peer.\n3. **Prevent Unsolicited Sync Floods**: Unsolicited RSR packets are rejected.\n\n## Protocol Changes\n\n### Binary Protocol Updates\n* **New Flag**: `IS_RSR` (0x10) added to the packet header flags.\n* **BitchatPacket**: Updated to include `isRSR: Bool` field.\n* **Encoding/Decoding**: Updated `BinaryProtocol` to handle the new flag.\n\n### Request Sync Payload\nThe `REQUEST_SYNC` packet payload (TLV encoded) has been updated to include:\n* **Future Filters**:\n * `sinceTimestamp` (Type 0x05): To request packets since a certain time (UInt64 big-endian).\n * `fragmentIdFilter` (Type 0x06): To request specific fragments (UTF-8 string).\n\n## Architecture\n\n### RequestSyncManager\nA new component (`Sync/RequestSyncManager.swift`) responsible for:\n* **Tracking**: Stores `peerID -> timestamp` mappings for pending sync requests.\n* **Validation**: `isValidResponse(from: PeerID, isRSR: Bool)` checks if an incoming RSR packet matches a pending request within the 30-second window.\n* **Cleanup**: Periodically removes expired requests.\n\n### GossipSyncManager Updates\n* **Unicast Sync**: Instead of blind broadcasting, the periodic sync task now iterates over connected peers and sends unicast `REQUEST_SYNC` packets.\n* **Registration**: Before sending, requests are registered with `RequestSyncManager`.\n* **Response Marking**: When responding to a `REQUEST_SYNC`, generated packets (Announce/Message) are explicitly marked with `isRSR = true` (and `ttl = 0`).\n\n### BLEService (Security Manager) Updates\n* **Timestamp Enforcement**: Checks `abs(now - packetTimestamp) < 2 minutes` for standard packets.\n* **Conditional Exemption**: If `packet.isRSR` is true (or packet is a legacy TTL=0 response), it queries `RequestSyncManager`.\n * **Valid**: If solicited, timestamp check is skipped (allowing historical data sync).\n * **Invalid**: If unsolicited or timed out, the packet is rejected.\n\n## Usage\n\nThese changes are integrated into `BLEService` and `GossipSyncManager`. No external API changes are required for clients, but all peers must be updated to support the new `IS_RSR` flag and protocol logic to participate in the secure sync process.\n" }, { "path": "docs/SOURCE_ROUTING.md", "content": "# Source-Based Routing for BitChat Packets (v2)\n\nThis document specifies the Source-Based Routing extension (v2) for the BitChat protocol. This upgrade enables efficient unicast routing across the mesh by allowing senders to specify an explicit path of intermediate relays.\n\n**Status:** Implemented in Android and iOS. Backward compatible (v1 clients ignore routing data).\n\n---\n\n## 1. Protocol Versioning & Layering\n\nTo support source routing and larger payloads, the packet format has been upgraded to **Version 2**.\n\n* **Version 1 (Legacy):** 2-byte payload length limit. Ignores routing flags.\n* **Version 2 (Current):** 4-byte payload length limit. Supports Source Routing.\n\n**Key Rule:** The `HAS_ROUTE (0x08)` flag is **only valid** if the packet `version >= 2`. Relays receiving a v1 packet must ignore this flag even if set.\n\n---\n\n## 2. Packet Structure Comparison\n\nThe following diagram illustrates the structural differences between a standard v1 packet and a source-routed v2 packet.\n\n### V1 Packet (Legacy)\n```text\n+-------------------+---------------------------------------------------------+\n| Fixed Header (14) | Variable Sections |\n+-------------------+----------+-------------+------------------+-------------+\n| Ver: 1 (1B) | SenderID | RecipientID | Payload | Signature |\n| Type, TTL, etc. | (8B) | (8B) | (Length in Head) | (64B) |\n| Len: 2 Bytes | | (Optional) | | (Optional) |\n+-------------------+----------+-------------+------------------+-------------+\n```\n\n### V2 Packet (Source Routed)\n```text\n+-------------------+-----------------------------------------------------------------------------+\n| Fixed Header (16) | Variable Sections |\n+-------------------+----------+-------------+-----------------------+------------------+-------------+\n| Ver: 2 (1B) | SenderID | RecipientID | SOURCE ROUTE | Payload | Signature |\n| Type, TTL, etc. | (8B) | (8B) | (Variable) | (Length in Head) | (64B) |\n| Len: 4 Bytes | | (Required*) | Only if HAS_ROUTE=1 | | (Optional) |\n+-------------------+----------+-------------+-----------------------+------------------+-------------+\n```\n\n**(*) Note:** A `Route` can be attached to **any** packet type that has a `RecipientID` (flag `HAS_RECIPIENT` set).\n\n### Fixed Header Differences\n\n| Field | Size (v1) | Size (v2) | Description |\n|---|---|---|---|\n| **Version** | 1 byte | 1 byte | `0x01` vs `0x02` |\n| **Payload Length** | **2 bytes** | **4 bytes** | `UInt32` in v2 to support large files. **Excludes** route/IDs/sig. |\n| **Total Size** | **14 bytes** | **16 bytes** | V2 header is 2 bytes larger. |\n\n---\n\n## 3. Source Route Specification\n\nThe `Source Route` field is a variable-length list of **intermediate hops** that the packet must traverse.\n\n* **Location:** Immediately follows `RecipientID`.\n* **Structure:**\n * `Count` (1 byte): Number of intermediate hops (`N`).\n * `Hops` (`N * 8` bytes): Sequence of Peer IDs.\n\n### Intermediate Hops Only\nThe route list MUST contain **only** the intermediate relays between the sender and the recipient.\n* **DO NOT** include the `SenderID` (it is already in the packet).\n* **DO NOT** include the `RecipientID` (it is already in the packet).\n\n**Example:**\nTopology: `Alice (Sender) -> Bob -> Charlie -> Dave (Recipient)`\n* Packet `SenderID`: Alice\n* Packet `RecipientID`: Dave\n* Packet `Route`: `[Bob, Charlie]` (Count = 2)\n\n---\n\n## 4. Topology Discovery (Gossip)\n\nTo calculate routes, nodes need a view of the network topology. This is achieved via a **Neighbor List** extension to the `IdentityAnnouncement` packet.\n\nThe `ANNOUNCE` packet payload now consists of a sequence of TLVs. The standard identity information is followed by an optional Gossip TLV.\n\n* **Mechanism:** Appended to the `IdentityAnnouncement` payload.\n* **New TLV Type:** `0x04` (Direct Neighbors).\n* **Content:** A list of Peer IDs that the announcing node is directly connected to.\n\n**TLV Structure (Type 0x04):**\n```text\n[Type: 0x04] [Length: 1B] [NeighborID1 (8B)] [NeighborID2 (8B)] ...\n```\nThe `Length` field indicates the total size of the neighbor IDs in bytes (N * 8). There is no explicit count field.\n\nNodes receiving this TLV update their local mesh graph, linking the sender to the listed neighbors.\n\n### Edge Verification (Two-Way Handshake)\n\nTo prevent spoofing and routing through stale connections, the Mesh Graph service implements a strict two-way handshake verification:\n\n* **Unconfirmed Edge:** If Peer A announces Peer B, but Peer B does *not* announce Peer A, the connection is treated as **unconfirmed**. Unconfirmed edges are visualized as dotted lines in debug tools but are **excluded** from route calculations.\n* **Confirmed Edge:** An edge is only valid for routing when **both** peers explicitly announce each other in their neighbor lists. This ensures that the connection is bidirectional and currently active from both perspectives.\n\n---\n\n## 5. Fragmentation & Source Routing\n\nWhen a large source-routed packet (e.g., File Transfer) exceeds the MTU and requires fragmentation:\n\n1. **Version Inheritance:** All fragments MUST be marked as **Version 2**.\n2. **Route Inheritance:** All fragments MUST contain the **exact same Route field** as the parent packet.\n\n**Why?** If fragments were sent as v1 packets or without routes, they would fall back to flooding, negating the bandwidth benefits of source routing for large data transfers.\n\n---\n\n## 6. Security & Signing\n\nSource routing is fully secured by the existing Ed25519 signature scheme.\n\n* **Scope:** The signature covers the **entire packet structure** (Header + Sender + Recipient + Route + Payload).\n* **Verification:** The receiver verifies the signature against the `SenderID`'s public key.\n* **Integrity:** Any tampering with the route list by malicious relays will invalidate the signature, causing the packet to be dropped by the destination.\n\n**Signature Input Construction:**\nSerialize the packet exactly as transmitted, but temporarily set `TTL = 0` and remove the `Signature` bytes.\n\n---\n\n## 7. Relay Logic\n\nWhen a node receives a packet **not** addressed to itself:\n\n1. **Check Route:**\n * Is `Version >= 2`?\n * Is `HAS_ROUTE` flag set?\n * Is the route list non-empty?\n2. **If YES (Source Routed):**\n * Find local Peer ID in the route list at index `i`.\n * **Next Hop:** The peer at `i + 1`.\n * **Last Hop:** If `i` is the last index, the Next Hop is the `RecipientID`.\n * **Action:** Attempt to unicast (`sendToPeer`) to the Next Hop.\n * **Fallback:** If the Next Hop is unreachable, **fall back to broadcast/flood** to ensure delivery.\n3. **If NO (Standard):**\n * Flood the packet to all connected neighbors (subject to TTL and probability rules).\n" }, { "path": "docs/TOR-INTEGRATION.md", "content": "Tor-by-default integration (scaffold)\n\nOverview\n- All network traffic is routed via a local Tor SOCKS5 proxy by default, with fail-closed behavior when Tor isn’t ready.

For local development only, define BITCHAT_DEV_ALLOW_CLEARNET to bypass Tor.\n- TorURLSession\n - Provides a shared URLSession configured with a SOCKS5 proxy when Tor is enforced/ready.\n - NostrRelayManager and GeoRelayDirectory now use this session and await Tor readiness before starting network activity.\n\nDrop‑in steps\n1) Build or obtain a small Tor framework\n - Recommended: Tor C (client-only) with static linking and dead-strip.\n - Configure Tor with a minimal feature set:\n ./configure \\\n --enable-static \\\n --disable-asciidoc --disable-unittests --disable-manpage \\\n --disable-zstd --disable-lzma --enable-zlib \\\n --disable-systemd --disable-ptrace --disable-seccomp\n CFLAGS=\"-Os -fdata-sections -ffunction-sections\" \\\n LDFLAGS=\"-Wl,-dead_strip\"\n - Build a tiny OpenSSL/LibreSSL (no engines, strip symbols) or reuse system crypto where permitted on macOS.\n\n2) Add the framework to Xcode targets\n - Drop your xcframework into `Frameworks/`. The project is prewired in `project.yml` to link/embed `Frameworks/tor-nolzma.xcframework` (rename yours to match, or update the path).\n - Ensure the binary includes the slices you need (iOS device/simulator and/or macOS). If your xcframework lacks simulator slices, you can still build/run on device or macOS arm64; simulator will fail to link.\n - On iOS, it will be embedded and signed automatically.\n\n3) Wire Tor bootstrap in TorManager.startTor()\n - Two paths are already implemented:\n - If a module named `Tor` is present (iCepa API), it starts `TORThread` directly.\n - Otherwise, it attempts a dynamic load (`dlopen`) of a bundled framework binary named `tor-nolzma.framework/tor-nolzma` (or `Tor.framework/Tor`), resolves `tor_run_main`, and launches Tor on a background thread.\n - `TorManager` writes a torrc and then probes `127.0.0.1:39050` until ready.\n\n4) Verify networking\n - On app launch, TorManager.startIfNeeded() is called implicitly by awaitReady().\n - NostrRelayManager.connect() awaits readiness, then creates WebSocket tasks via TorURLSession.shared.\n - GeoRelayDirectory.fetchRemote() awaits readiness, then fetches via TorURLSession.shared.\n\n5) Optional macOS optimization\n - Detect a system Tor binary (e.g., /opt/homebrew/bin/tor) and run it as a subprocess to avoid bundling.

No device name, no plaintext identity beyond what the user broadcasts.\n- Discovery and flooding incorporate jitter and TTL caps to reduce linkability and propagation radius of encrypted payloads.\n- UI and storage remain ephemeral; message content is not persisted to disk. Minimal state (e.g., read-receipt IDs) is stored for UX and is bounded/cleaned.\n- Logging defaults to conservative levels; debug verbosity is suppressed for release builds. A single env var can raise/lower threshold when needed.\n\nBLE Privacy Considerations\n- Announce content: Unchanged — nickname + Noise public key only.\n- Local Name: Not used (explicitly disabled). Avoids leaking device/OS identity.\n- Address: iOS uses BLE MAC randomization; BitChat does not attempt to set static addresses.\n- Announce jitter: Each announce is delayed by a small random jitter to avoid synchronization-based correlation.\n- Scanning: Foreground scanning uses “allow duplicates” briefly to improve discovery latency; background uses standard scanning parameters.\n- RSSI gating: The acceptance threshold adapts to nearby density (approx. -95 to -80 dBm) to reduce long-distance observations in dense areas and improve connectivity in sparse ones.\n- Fragmentation: Fragments use write-with-response for reliability (less re-broadcast churn = fewer repeated signals).\n- GATT permissions: Private characteristic disallows .read; we use notify/write/writeWithoutResponse to avoid exposing plaintext attributes over GATT.\n\nMesh Routing and Multi-hop Limits\n- Encrypted relays permitted with random per-hop delay (small jitter) to smooth floods.\n- TTL cap: Encrypted payloads are capped at 2 hops, limiting metadata spread and path reconstruction risk while enabling close-range relays.\n\nNostr Private Messaging Fallback\n- Usage criteria: Only attempted for mutual favorites or where a Nostr key has been exchanged (stored in favorites).\n- Payload confidentiality: Messages embed a BitChat Noise-encrypted packet inside a NIP-17 gift wrap; relays see only random-looking ciphertext.\n- Timestamp handling: Gift wraps add small randomized offsets to reduce exact timing correlation.\n- Read/delivery acks: Also encapsulated in gift wraps, preserving content secrecy and minimizing metadata.\n- Relay policy variance: Some relays apply “web-of-trust” policies and may reject events; BitChat tolerates partial delivery and still prefers mesh when available.\n\nRead Receipts and Delivery Acks\n- Routing policy: Prefer mesh if Noise session established; otherwise use Nostr when mapping exists.\n- Throttling: Nostr READ acks are queued and rate-limited (~3/s) to prevent relay rate limits during backlogs.\n- Coalescing (optional future): When entering a chat with many unread, only send READ for the latest message, marking older as read locally to reduce metadata.\n\nData Retention and State\n- Messages: Ephemeral in-memory only; history is bounded per chat and trimmed.\n- Read-receipt IDs: Stored in `UserDefaults` for UX continuity; periodically pruned to IDs present in memory.\n- Favorites: Noise and optional Nostr keys with petnames; can be wiped via panic action.\n- Panic: Triple-tap clears keys, sessions, cached state, and disconnects transports.\n\nLogging and Telemetry\n- Centralized `SecureLogger` filters potential secrets and uses OSLog privacy markers.\n- Default level: `info`; release builds suppress debug. Developers can set `BITCHAT_LOG_LEVEL=debug|info|warning|error|fault`.\n- Transport routing, ACK sends, subscribe/connect noise were downgraded from info→debug.\n- OS/system errors (e.g., transient WebSocket disconnects) may still appear in system logs; BitChat avoids re-logging those unless actionable.\n\nResidual Risks and Mitigations\n- RF fingerprinting: BLE presence is observable at the RF layer; mitigated by minimal announce content and platform MAC randomization.\n- Timing correlation: Announce/relay jitter reduces but does not eliminate timing analysis.
