Which step am I missing - DES-OFB Key
#7
Thanks atom,

That was exactly to approach I had thought, because the key never changes, while there may be numerous keys that produce a C4 value with the IV, there will be a significantly smaller number that when using the same key with the second IV will produce CC, and so on. If it doesn't, discard the key and start again until it does.

I am yet to dive into any of the code. To achieve this are we talking major changes or will it be a relatively straight forward tweak?
