(Well, OK, that's a bit absolute, there may be thousands of people out there who've tried to do this and given up that we don't know about, but somehow I doubt it. When I did SSL it was so obviously a ladder diagram that I just ignored all the state-machine stuff in the spec and implemented the protocol as such. My implementation couldn't be made vulnerable to the recent OpenSSL issue without rewriting half the code). Peter.
