MiniZip - Copyright (c) 1998-2010 - by Gilles Vollant - version 1.1 64 bits from Mathias Svensson
Introduction
---------------------
MiniZip 1.1 is built from MiniZip 1.0 by Gilles Vollant ( http://www.winimage.com/zLibDll/minizip.html )
When adding ZIP64 support into minizip it would result into risk of breaking compatibility with minizip 1.0.
All possible work was done for compatibility.
Background
---------------------
When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64
support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ )
That was used as a starting point. And after that ZIP64 support was added to zip.c
some refactoring and code cleanup was also done.
Changed from MiniZip 1.0 to MiniZip 1.1
---------------------------------------
* Added ZIP64 support for unzip ( by Even Rouault )
* Added ZIP64 support for zip ( by Mathias Svensson )
* Reverted some changed that Even Rouault did.
* Bunch of patches received from Gulles Vollant that he received for MiniZip from various users.
* Added unzip patch for BZIP Compression method (patch create by Daniel Borca)
* Added BZIP Compress method for zip
* Did some refactoring and code cleanup
Credits
Gilles Vollant - Original MiniZip author
Even Rouault - ZIP64 unzip Support
Daniel Borca - BZip Compression method support in unzip
Mathias Svensson - ZIP64 zip support
Mathias Svensson - BZip Compression method support in zip
Resources
ZipLayout http://result42.com/projects/ZipFileLayout
Command line tool for Windows that shows the layout and information of the headers in a zip archive.
Used when debugging and validating the creation of zip files using MiniZip64
ZIP App Note http://www.pkware.com/documents/casestudies/APPNOTE.TXT
Zip File specification
Notes.
* To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

/* 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)

.SH NAME
miniunzip - uncompress and examine ZIP archives
.SH SYNOPSIS
.B miniunzip
.RI [ -exvlo ]
zipfile [ files_to_extract ] [-d tempdir]
.SH DESCRIPTION
.B minizip
is a simple tool which allows the extraction of compressed file
archives in the ZIP format used by the MS-DOS utility PKZIP. It was
written as a demonstration of the
.IR zlib (3)
library and therefore lack many of the features of the
.IR unzip (1)
program.
.SH OPTIONS
A number of options are supported. With the exception of
.BI \-d\ tempdir
these must be supplied before any
other arguments and are:
.TP
.BI \-l\ ,\ \-\-v
List the files in the archive without extracting them.
.TP
.B \-o
Overwrite files without prompting for confirmation.
.TP
.B \-x
Extract files (default).
.PP
The
.I zipfile
argument is the name of the archive to process. The next argument can be used
to specify a single file to extract from the archive.
Lastly, the following option can be specified at the end of the command-line:
.TP
.BI \-d\ tempdir
Extract the archive in the directory
.I tempdir
rather than the current directory.
.SH SEE ALSO
.BR minizip (1),
.BR zlib (3),
.BR unzip (1).
.SH AUTHOR
This program was written by Gilles Vollant. This manual page was
written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option
was added by Dirk Eddelbuettel <edd@debian.org>.

.SH NAME
minizip - create ZIP archives
.SH SYNOPSIS
.B minizip
.RI [ -o ]
zipfile [ " files" ... ]
.SH DESCRIPTION
.B minizip
is a simple tool which allows the creation of compressed file archives
in the ZIP format used by the MS-DOS utility PKZIP. It was written as
a demonstration of the
.IR zlib (3)
library and therefore lack many of the features of the
.IR zip (1)
program.
.SH OPTIONS
The first argument supplied is the name of the ZIP archive to create or
.RI -o
in which case it is ignored and the second argument treated as the
name of the ZIP file. If the ZIP file already exists it will be
overwritten.
.PP
Subsequent arguments specify a list of files to place in the ZIP
archive. If none are specified then an empty archive will be created.

Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
Modifications of Unzip for Zip64
Copyright (C) 2007-2008 Even Rouault
Modifications for Zip64 support on both zip and unzip
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
------------------------------------------------------------------------------------
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

/* zip.c -- IO on .zip files using zlib
Version 1.1, February 14h, 2010
part of the MiniZip project - ( http://www.winimage.com/zLibDll/minizip.html )
Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
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 automatically 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
