[DUG] Enryption

[Kyley Harris]

Sorry, to answer your question, the CBC is more secure, and the initvector
is basically a piece of data to start the encryption chain because of the
way CBC works by using a previous segment of data to encrypt the next.. so
you would create a piece of data.. consider it like a password.. if you try
to decrypt with the wrong init vector.. then you get garbage.
