Subject:Encrypted zipfiles
Time:11:46 pm.
SOLVED: Fixed my own problem when I found the svn url.
http://svn.python.org/projects/python/trunk/Lib/zipfile.py

One of the data venders I work with has a somewhat weird security system. Ftp access is anonymous, but client folders are hidden to all but direct chdir calls. Then to make things fun, the data comes in 12 zip files totally 800-1.2GB (varies by market activity). The kicker is that the zips are key password encrypted. Unfortunately it looks like the core python zip libraries are lacking password decryption facilities for now... but there is hope.

I found a diff message that looks like it adds the needed decryption support, but I have no idea where to find a beta/alpha of this on python.org. Anyone have any ideas?

Also I know about chiklets zip module, and the price really isn't that bad, but my department's tools/materials budget is going towards another way higher priority project right now...so I am stuck and my hope is that I can find a release candidate or something.    Also I tried the ziparchive module found on source forge, but it has a bug in its decryption code that I don't have ability to debug.
