I'm hoping to add BZIP2 compression to zipfile for 2.5. My primary motivation is that Project Gutenberg seems to be starting to use BZIP2 compression for some of its zips. What other wish list things do people around here have for zipfile? I thought I'd collect input here and make a PEP.
Encryption/decryption support. Will most likely require a C extension since the algorithm relies on ints (or longs, don't remember) wrapping around when the value becomes too large.
I'm trying to use byte-block streams (iterators taking iterables) as the basic structure of getting data in and out. I think the encryption/ decryption can then be plugged in at the right point. If it can be set up properly, you can import the encryption separately and connect it to zipfiles with a call. Would this address what you want? I believe there is an issue actually building in the encryption/decryption in terms of redistribution.
Possibly. Encryption is part of the PKZIP spec so I was just thinking of covering that, not adding external encryption support. It really is not overly complex stuff, just will want to do it in C for speed probably as Guido suggested (but, as always, I would profile that first to see if performance is really that bad).
