one? Also, a ballpark guess of how this result extrapolates to the MIPS years required to factor a 512 bit PGP key would probably be of interest to all.
I don't have a good guess for this, but Arjen did say that the cost to break RSA-130 was a fraction of what it cost to break RSA-129 because of the improved algorithm, so I'd guess we'll find out soon. The next target of the consortium is planned to be RSA-155, I believe, which is above 512 bits; that means skipping RSA-140 to go for the one with the higher psychological value. While 512-bit PGP keys are interesting to Cypherpunks, other 512-bit RSA keys are vitally important to some banks. Jim Gillogly Trewesday, 25 Astron S.R. 1996, 07:50
