|
||||
+
|
||||
+ 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.
