A 307 digit number is 1024 bits, near enough. 1024 bits was scheduled to fail in 2013. It has failed early, due to modest advances in factorization.
Thus past comparisons of the strength of encryption key sizes are no longer entirely accurate. Further, they never were that accurate to start with - one needs actual run times for breaks run on the same machine. None of the past comparisons have started from such concrete data. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
