ok - I just read part of the paper. I'm not a cryptographer but I am a mathemetician and here are some trivial conclusions. the algorithm is looking for a number: N where N=p*q for two primes p and q of relatively the same size. If you look at the _original_ equations developed by Pohlig-Hellm

OpenSSL so far is patent free and probably will remain generally so unless some hotshot chooses to try to patent something which has already been done - but they don't know about. This has happened - I have examples. RSA's stuff is patented in the US only and it expires as you say in Sept. Thus
