in reply to Crypt::CBC and varying the key
Hi
If I understand you correctly, you're not doing CBC (cipher block chaining). See this article in Wikipedia. If you are doing CBC, you only need a key and one initialiation vector (IV). The "chaining" is to use the previous block as the IV for the next block before encrypting with the key.
CBC allows you to chain together a message that is bigger than the block size as one unit. Is this not what you want?
Hope this helps, J
