++ This code is a modified version of crypting code in Infozip distribution

++ The encryption/decryption parts of this source code (as opposed to 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

++ 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
