More bad news... The Kalyna team got back to us with test vectors for other modes (formerly we only had them for ECB). CBC encryption looks good, but CBC decryption is sideways. Both NoPadding and PKCSPadding are producing bad results. I have not identified the issue yet, but I don't believe its a simple memory error. If the initial survey is correct, then it looks like a filter problem. I think there's a bad interaction between the VariableBlockSize gear and the existing framework. I think the worse case is, we have to fold VariableBlockSize into SimpleKeyingInterface. That's kind of how the library is wired (nearly everything with a symmetric key depends on SimpleKeyingInterface). I tired to avoid polluting SimpleKeyingInterface by keeping VariableBlockSize separate, but it may not be a viable solution. The best case is I missed something obvious, like an override somewhere. But its not jumping out at me. Jeff -- -- You received this message because you are subscribed to the "Crypto++ Users" Google Group.
