Is it possible to estimate the approximate duration of a factorization for rsa-309 (1024 bit rsa)? How long will it take to find good polynoms? (for example on...
... Sorry I don't know the answer to this, but I am also curious about RSA-155 now that it has been almost 10 years since the first 512bit RSA key was publicly...

How do I run factmsieve.pl? I can factor using factlat.pl with no problems, using the latest core 2 distribution. factmsieve terminates after a short print out...
... Usually you run it just like factlat.pl. There are a couple of gotchas in the script. First, of course, is to put a working binary of msieve (or msieve.exe...

Summary of the problem. GGNFS crashes 85% of the time on C85-C115 factorisations when run through fact*.pl (* is Lat or Msieve) due to pol51m0b failure. The ...
