# SSZipArchive
SSZipArchive is a simple utility class for zipping and unzipping files. Features:
* Unzipping zip files
* Unzipping password protected zip files
* Creating zip files
* Appending to zip files
* Zipping files
* Zipping NSData with a filename
* Works in ARC and non-ARC projects
## Adding to your project
1. Add `SSZipArchive.h`, `SSZipArchive.m`, and `minizip` to your project.
2. Add the `libz` library to your target
You don't need to do anything regarding ARC. SSZipArchive will detect if you're not using ARC and add the required memory management code.
## Usage
``` objective-c
// Unzipping
NSString *zipPath = @"path_to_your_zip_file";
NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
// Zipping
NSString *zippedPath = @"path_where_you_want_the_file_created";
NSArray *inputPaths = [NSArray arrayWithObjects:
[[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
[[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
nil];
[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];
```
## License

A slightly modified version of [Minizip](http://www.winimage.com/zLibDll/minizip.html) 1.1 is also included and is licensed under the [Zlib license](http://www.zlib.net/zlib_license.html).
## Thanks
Thanks [aish](http://code.google.com/p/ziparchive) for creating [ZipArchive](http://code.google.com/p/ziparchive) which SSZipArchive is based on, Johnnie Walker ([@randomsequence](https://github.com/randomsequence)) for implementing creation support, and John Engelhart ([@johnezang](https://github.com/johnezang)) for all his amazing help along the way.

/* crypt.h -- base code for crypt/uncrypt ZIPfile
Version 1.01e, February 12th, 2005
Copyright (C) 1998-2005 Gilles Vollant
This code is a modified version of crypting code in Infozip distribution
The encryption/decryption parts of this source code (as opposed to the
non-echoing password parts) were originally written in Europe. The
whole source package can be freely distributed, including from the USA.
(Prior to January 2000, re-export from the US was a violation of US law.)
This encryption code is a direct transcription of the algorithm from
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
file (appnote.txt) is distributed with the PKZIP program (even in the
version without encryption capabilities).
If you don't need crypting in your application, just define symbols
NOCRYPT and NOUNCRYPT.
This code support the "Traditional PKWARE Encryption".
The new AES encryption added on Zip format by Winzip (see the page
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
Encryption is not supported.

Changes
Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
More if/def section may be needed to support other platforms
Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
(but you should use iowin32.c for windows instead)

------------------------------------------------------------------------------------
Decryption code comes from crypt.c by Info-ZIP but has been greatly reduced in terms of
compatibility with older software. The following is from the original crypt.c.
Code woven in by Terry Thorsen 1/2003.
Copyright (c) 1990-2000 Info-ZIP. All rights reserved.
See the accompanying file LICENSE, version 2000-Apr-09 or later
(the contents of which are also included in zip.h) for terms of use.
If, for some reason, all these files are missing, the Info-ZIP license
also may be found at: ftp://ftp.info-zip.org/pub/infozip/license.html
crypt.c (full version) by Info-ZIP. Last revised: [see crypt.h]
The encryption/decryption parts of this source code (as opposed to the
non-echoing password parts) were originally written in Europe. The
whole source package can be freely distributed, including from the USA.
(Prior to January 2000, re-export from the US was a violation of US law.)
This encryption code is a direct transcription of the algorithm from
Roger Schlafly, described by Phil Katz in the file appnote.txt. This
file (appnote.txt) is distributed with the PKZIP program (even in the
version without encryption capabilities).
------------------------------------------------------------------------------------
Changes in unzip.c
2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos
2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz*
2007-2008 - Even Rouault - Remove old C style function prototypes
2007-2008 - Even Rouault - Add unzip support for ZIP64
Copyright (C) 2007-2008 Even Rouault
Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again).
Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G
should only read the compressed/uncompressed size from the Zip64 format if
the size from normal header was 0xFFFFFFFF
Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant
Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required)
Patch created by Daniel Borca
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer

Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
Changes
Oct-2009 - Mathias Svensson - Remove old C style function prototypes
Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
It is used when recreting zip archive with RAW when deleting items from a zip.
ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer
