/* crypt.h -- base code for traditional PKWARE encryption

This code is a modified version of crypting code in Info-ZIP distribution
Copyright (C) 1990-2000 Info-ZIP. All rights reserved.
See the Info-ZIP LICENSE file version 2000-Apr-09 or later for terms of use
which also may be found at: ftp://ftp.info-zip.org/pub/infozip/license.html
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 program is distributed under the terms of the same license as zlib.

Modifications for Zip64 support
Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
For more info read MiniZip_info.txt
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)
