Hi guys, I was just wondering if this idea makes sense overall or if there are major impediments (indexing performance ?):

Use v2.0's zlib plugin as an example. Encryption/decryption should work in a very similar way. I think someone's already attempted to write something like that, but no one's yet at least made such code public.

Only problem is if something wants access to mails without knowing the password. But that's probably a feature. :) In such case you could just make your istream return -EIO error (instead of returning encrypted data).
