So does it just mean that the implementation is hard to get right? I'm all for killing off ideas, especially when it comes to cryptography, but I'd like to at least learn something in the process. Is there somewhere I can learn about everything that can go wrong with that specific process, or would I have to just try to implement this algorithms myself, to understand the risks? BTW. Thanks for everything so far; I trust you're a busy man.
