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.
