-/* crypt.h -- base code for crypt/uncrypt ZIPfile
-
-
-Version 1.01, May 8th, 2004
-
-Copyright (C) 1998-2004 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.
