+
+ 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.
