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. -- -- Scott David Daniels [EMAIL PROTECTED] ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

The issue primarily exists in the U.S., and there are now (U.S.) official procedures to deal with them, and the PSF can and does follow these procedures.

I thought I'd collect input here and make a PEP. I can open a pseudo-file for STORED files in binary read mode, for example, to allow reading zip-in-zip files without fully occupying memory. I'm not sure that zipfile needs BZIP2 support...being that there is a bzip2 module. - Josiah ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/python-python-dev%40m.gmane.org But if you look at the zipfile document, BZIP2 is a compression technique you can use (per file) in a zip archive. In fact, I use bz2 to compress/decompress, but the data still needs to inhabit the archive. -- -- Scott David Daniels [EMAIL PROTECTED] ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
