To help you resolve your issue faster please make sure you have done the following: * Searched existing issues (even closed ones) for your same problem * Make sure you have installed the required dependencies listed on the readme * Read your npm error log for lines telling you what failed, usually it is a problem with not having the correct dependencies installed to build the native module Once you have done the above and are still confident that the issue is with the module, please describe it below. Some things that really help get your issue resolved faster are: * What went wrong? * What did you expect to happen? * Which version of nodejs and OS? * If you find a bug, please write a failing test. Thanks! P.S. If it doesn't look like you read the above then your issue will likely be closed without further explanation. Sorry, but there are just too many issues opened with no useful information or questions which have been previously addressed. ================================================ FILE: LICENSE ================================================ Copyright (c) 2010 Nicholas Campbell Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

You can read about [bcrypt in Wikipedia][bcryptwiki] as well as in the following article: [How To Safely Store A Password][codahale] ## If You Are Submitting Bugs or Issues Please verify that the NodeJS version you are using is a _stable_ version; Unstable versions are currently not supported and issues created while using an unstable version will be closed. If you are on a stable version of NodeJS, please provide a sufficient code snippet or log files for installation issues. The code snippet does not require you to include confidential information. However, it must provide enough information so the problem can be replicable, or it may be closed without an explanation. ## Version Compatibility _Please upgrade to at least v5.0.0 to avoid security issues mentioned below._ | Node Version | Bcrypt Version | | -------------- | ------------------| | 0.4 | <= 0.4 | | 0.6, 0.8, 0.10 | >= 0.5 | | 0.11 | >= 0.8 | | 4 | <= 2.1.0 | | 8 | >= 1.0.3 < 4.0.0 | | 10, 11 | >= 3 | | 12 onwards | >= 3.0.6 | | 18 onwards | >= 6.0.0 | `node-gyp` only works with stable/released versions of node. Since the `bcrypt` module uses `node-gyp` to build and install, you'll need a stable version of node to use bcrypt. If you do not, you'll likely see an error that starts with: ``` gyp ERR! stack Error: "pre" versions of node cannot be installed, use the --nodedir flag instead ``` ## Security Issues And Concerns > Per bcrypt implementation, only the first 72 bytes of a string are used. Any extra bytes are ignored when matching passwords. Note that this is not the first 72 *characters*. It is possible for a string to contain less than 72 characters, while taking up more than 72 bytes (e.g. a UTF-8 encoded string containing emojis). If a string is provided, it will be encoded using UTF-8. As should be the case with any security tool, anyone using this library should scrutinise it. If you find or suspect an issue with the code, please bring it to the maintainers' attention. We will spend some time ensuring that this library is as secure as possible. Here is a list of BCrypt-related security issues/concerns that have come up over the years. * An [issue with passwords][jtr] was found with a version of the Blowfish algorithm developed for John the Ripper. This is not present in the OpenBSD version and is thus not a problem for this module. HT [zooko][zooko]. * Versions `< 5.0.0` suffer from bcrypt wrap-around bug and _will truncate passwords >= 255 characters leading to severely weakened passwords_. Please upgrade at earliest. See [this wiki page][wrap-around-bug] for more details. * Versions `< 5.0.0` _do not handle NUL characters inside passwords properly leading to all subsequent characters being dropped and thus resulting in severely weakened passwords_. Please upgrade at earliest. See [this wiki page][improper-nuls] for more details. ## Compatibility Note This library supports `$2a$` and `$2b$` prefix bcrypt hashes. `$2x$` and `$2y$` hashes are specific to bcrypt implementation developed for John the Ripper. In theory, they should be compatible with `$2b$` prefix. Compatibility with hashes generated by other languages is not 100% guaranteed due to difference in character encodings. However, it should not be an issue for most cases. ### Migrating from v1.0.x Hashes generated in earlier version of `bcrypt` remain 100% supported in `v2.x.x` and later versions. In most cases, the migration should be a bump in the `package.json`. Hashes generated in `v2.x.x` using the defaults parameters will not work in earlier versions. ## Dependencies * NodeJS * `node-gyp` * Please check the dependencies for this tool at: https://github.com/nodejs/node-gyp * Windows users will need the options for c# and c++ installed with their visual studio instance. * Python 2.x/3.x * `OpenSSL` - This is only required to build the `bcrypt` project if you are using versions <= 0.7.7. Otherwise, we're using the builtin node crypto bindings for seed data (which use the same OpenSSL code paths we were, but don't have the external dependency). ## Install via NPM ``` npm install bcrypt ``` ***Note:*** OS X users using Xcode 4.3.1 or above may need to run the following command in their terminal prior to installing if errors occur regarding xcodebuild: ```sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer``` _Pre-built binaries for various NodeJS versions are made available on a best-effort basis._ Only the current stable and supported LTS releases (Node 18+) are actively tested against. _There may be an interval between the release of the module and the availability of the compiled modules._ Currently, we have pre-built binaries that support the following platforms: 1. Windows x64 and arm64 2. Linux x64 and arm64 (GlibC and musl) 3. macOS x64 and arm64 If you face an error like this: ``` node-pre-gyp ERR! Tried to download(404): https://github.com/kelektiv/node.bcrypt.js/releases/download/v1.0.2/bcrypt_lib-v1.0.2-node-v48-linux-x64.tar.gz ``` Make sure you have the appropriate dependencies installed and configured for your platform. You can find installation instructions for the dependencies for some common platforms [in this page][depsinstall]. ## Usage ### async (recommended) ```javascript const bcrypt = require('bcrypt'); const saltRounds = 10; const myPlaintextPassword = 's0/\/\P4$$w0rD'; const someOtherPlaintextPassword = 'not_bacon'; ``` #### To hash a password: Technique 1 (generate a salt and hash on separate function calls): ```javascript bcrypt.genSalt(saltRounds, function(err, salt) { bcrypt.hash(myPlaintextPassword, salt, function(err, hash) { // Store hash in your password DB. }); }); ``` Technique 2 (auto-gen a salt and hash): ```javascript bcrypt.hash(myPlaintextPassword, saltRounds, function(err, hash) { // Store hash in your password DB. }); ``` Note that both techniques achieve the same end-result. #### To check a password: ```javascript // Load hash from your password DB. bcrypt.compare(myPlaintextPassword, hash, function(err, result) { // result == true }); bcrypt.compare(someOtherPlaintextPassword, hash, function(err, result) { // result == false }); ``` [A Note on Timing Attacks](#a-note-on-timing-attacks) ### with promises bcrypt uses whatever `Promise` implementation is available in `global.Promise`. NodeJS has a native `Promise` implementation built in. However, this should work in any Promises/A+ compliant implementation. Async methods that accept a callback, return a `Promise` when the callback is not specified if Promise support is available. The Promise implementation can be customized using the `bcrypt.promises.use()` method: ```javascript // Example: Using a custom Promise implementation const bluebird = require('bluebird'); bcrypt.promises.use(bluebird); ``` ```javascript bcrypt.hash(myPlaintextPassword, saltRounds).then(function(hash) { // Store hash in your password DB. }); ``` ```javascript // Load hash from your password DB. bcrypt.compare(myPlaintextPassword, hash).then(function(result) { // result == true }); bcrypt.compare(someOtherPlaintextPassword, hash).then(function(result) { // result == false }); ``` This is also compatible with `async/await` ```javascript async function checkUser(username, password) { //... fetch user from a db etc. const match = await bcrypt.compare(password, user.passwordHash); if(match) { //login } //... } ``` ### ESM import ```javascript import bcrypt from "bcrypt"; // later await bcrypt.compare(password, hash); ``` ### sync ```javascript const bcrypt = require('bcrypt'); const saltRounds = 10; const myPlaintextPassword = 's0/\/\P4$$w0rD'; const someOtherPlaintextPassword = 'not_bacon'; ``` #### To hash a password: Technique 1 (generate a salt and hash on separate function calls): ```javascript const salt = bcrypt.genSaltSync(saltRounds); const hash = bcrypt.hashSync(myPlaintextPassword, salt); // Store hash in your password DB. ``` Technique 2 (auto-gen a salt and hash): ```javascript const hash = bcrypt.hashSync(myPlaintextPassword, saltRounds); // Store hash in your password DB. ``` As with async, both techniques achieve the same end-result. #### To check a password: ```javascript // Load hash from your password DB. bcrypt.compareSync(myPlaintextPassword, hash); // true bcrypt.compareSync(someOtherPlaintextPassword, hash); // false ``` [A Note on Timing Attacks](#a-note-on-timing-attacks) ### Why is async mode recommended over sync mode? We recommend using async API if you use `bcrypt` on a server. Bcrypt hashing is CPU intensive which will cause the sync APIs to block the event loop and prevent your application from servicing any inbound requests or events. The async version uses a thread pool which does not block the main event loop. ## API `BCrypt.` * `genSaltSync(rounds, minor)` * `rounds` - [OPTIONAL] - the cost of processing the data. (default - 10) * `minor` - [OPTIONAL] - minor version of bcrypt to use. (default - b) * `genSalt(rounds, minor, cb)` * `rounds` - [OPTIONAL] - the cost of processing the data. (default - 10) * `minor` - [OPTIONAL] - minor version of bcrypt to use. (default - b) * `cb` - [OPTIONAL] - a callback to be fired once the salt has been generated. If `cb` is not specified, a `Promise` is returned if Promise support is available. * `err` - First parameter to the callback detailing any errors. * `salt` - Second parameter to the callback providing the generated salt. * `hashSync(data, salt)` * `data` - [REQUIRED] - the data to be encrypted (string or Buffer). * `salt` - [REQUIRED] - the salt to be used to hash the password. If specified as a number then a salt will be generated with the specified number of rounds and used (see example under **Usage**). * `hash(data, salt, cb)` * `data` - [REQUIRED] - the data to be encrypted (string or Buffer). * `salt` - [REQUIRED] - the salt to be used to hash the password. If specified as a number then a salt will be generated with the specified number of rounds and used (see example under **Usage**). * `cb` - [OPTIONAL] - a callback to be fired once the data has been encrypted. If `cb` is not specified, a `Promise` is returned if Promise support is available. * `err` - First parameter to the callback detailing any errors. * `encrypted` - Second parameter to the callback providing the encrypted form. * `compareSync(data, encrypted)` * `data` - [REQUIRED] - data to compare (string or Buffer). * `encrypted` - [REQUIRED] - data to be compared to. * `compare(data, encrypted, cb)` * `data` - [REQUIRED] - data to compare (string or Buffer). * `encrypted` - [REQUIRED] - data to be compared to. * `cb` - [OPTIONAL] - a callback to be fired once the data has been compared. If `cb` is not specified, a `Promise` is returned if Promise support is available. * `err` - First parameter to the callback detailing any errors. * `same` - Second parameter to the callback providing whether the data and encrypted forms match [true | false]. * `getRounds(encrypted)` - return the number of rounds used to encrypt a given hash * `encrypted` - [REQUIRED] - hash from which the number of rounds used should be extracted. * `promises.use(promiseImplementation)` - change the Promise implementation that bcrypt uses * `promiseImplementation` - [REQUIRED] - a Promises/A+ compatible implementation to be used. ## A Note on Rounds A note about the cost: when you are hashing your data, the module will go through a series of rounds to give you a secure hash. The value you submit is not just the number of rounds the module will go through to hash your data. The module will use the value you enter and go through `2^rounds` hashing iterations. From @garthk, on a 2GHz core you can roughly expect: rounds=8 : ~40 hashes/sec rounds=9 : ~20 hashes/sec rounds=10: ~10 hashes/sec rounds=11: ~5 hashes/sec rounds=12: 2-3 hashes/sec rounds=13: ~1 sec/hash rounds=14: ~1.5 sec/hash rounds=15: ~3 sec/hash rounds=25: ~1 hour/hash rounds=31: 2-3 days/hash ## A Note on Timing Attacks Because it's come up multiple times in this project and other bcrypt projects, it needs to be said. The `bcrypt` library is not susceptible to timing attacks. From codahale/bcrypt-ruby#42: > One of the desired properties of a cryptographic hash function is preimage attack resistance, which means there is no shortcut for generating a message which, when hashed, produces a specific digest. A great thread on this, in much more detail can be found @ codahale/bcrypt-ruby#43 If you're unfamiliar with timing attacks and want to learn more you can find a great writeup @ [A Lesson In Timing Attacks][timingatk] However, the comparison function is _not_ time safe (constant-time), as it may exit early when a mismatch is found. Normally, this could enable a timing attack, but because it compares full bcrypt hash digests rather than raw passwords, and hashes are preimage-resistant, an attacker cannot gain any information about the stored hash. If you use the comparison function outside the bcrypt library, we cannot guarantee its security. Keep this in mind when using the library. ## Hash Info The characters that comprise the resultant hash are `./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789$`. Resultant hashes will be 60 characters long and they will include the salt among other parameters, as follows: `$[algorithm]$[cost]$[salt][hash]` - 2 chars hash algorithm identifier prefix. `"$2a$" or "$2b$"` indicates BCrypt - Cost-factor (n). Represents the exponent used to determine how many iterations 2^n - 16-byte (128-bit) salt, base64 encoded to 22 characters - 24-byte (192-bit) hash, base64 encoded to 31 characters Example: ``` $2b$10$nOUIs5kJ7naTuTFkBy1veuK0kSxUFXfuaOKdOKf9xYT0KKIGSJwFa | | | | | | | hash-value = K0kSxUFXfuaOKdOKf9xYT0KKIGSJwFa | | | | | salt = nOUIs5kJ7naTuTFkBy1veu | | | cost-factor => 10 = 2^10 rounds | hash-algorithm identifier => 2b = BCrypt ``` ## Testing If you create a pull request, tests better pass :) ``` npm install npm test ``` ## Credits The code for this comes from a few sources: * blowfish.cc - OpenBSD * bcrypt.cc - OpenBSD * bcrypt::gen_salt - [gen_salt inclusion to bcrypt][bcryptgs] * bcrypt_node.cc - me ## Contributors * [Antonio Salazar Cardozo][shadowfiend] - Early MacOS X support (when we used libbsd) * [Ben Glow][pixelglow] - Fixes for thread safety with async calls * [Van Nguyen][thegoleffect] - Found a timing attack in the comparator * [NewITFarmer][newitfarmer] - Initial Cygwin support * [David Trejo][dtrejo] - packaging fixes * [Alfred Westerveld][alfredwesterveld] - packaging fixes * [Vincent Côté-Roy][vincentr] - Testing around concurrency issues * [Lloyd Hilaiel][lloyd] - Documentation fixes * [Roman Shtylman][shtylman] - Code refactoring, general rot reduction, compile options, better memory management with delete and new, and an upgrade to libuv over eio/ev. * [Vadim Graboys][vadimg] - Code changes to support 0.5.5+ * [Ben Noordhuis][bnoordhuis] - Fixed a thread safety issue in nodejs that was perfectly mappable to this module. * [Nate Rajlich][tootallnate] - Bindings and build process. * [Sean McArthur][seanmonstar] - Windows Support * [Fanie Oosthuysen][weareu] - Windows Support * [Amitosh Swain Mahapatra][recrsn] - $2b$ hash support, ES6 Promise support * [Nicola Del Gobbo][NickNaso] - Initial implementation with N-API ## License Unless stated elsewhere, file headers or otherwise, the license as stated in the LICENSE file.
