Hi<p>
If I understand you correctly, you're not doing CBC (cipher block chaining). See this <a href="http://en.wikipedia.org/wiki/Cipher-block_chaining">article</a> 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.<p>
CBC allows you to chain together a message that is bigger than the block size as one unit. Is this not what you want?</p>
Hope this helps, J
