/* crypt.h -- base code for traditional PKWARE encryption
Version 1.01e, February 12th, 2005
Copyright (C) 1998-2005 Gilles Vollant
Modifications for Info-ZIP crypting
Copyright (C) 2003 Terry Thorsen
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.

/* ioapi_mem.h -- IO base function header for compress/uncompress .zip
files using zlib + zip or unzip API
This version of ioapi is designed to access memory rather than files.
We do use a region of memory to put data in to and take it out of. We do
not have auto-extending buffers and do not inform anyone else that the
data has been written. It is really intended for accessing a zip archive
embedded in an application such that I can write an installer with no
external files. Creation of archives has not been attempted, although
parts of the framework are present.
