WHOA, RSA230 is cracked. Very interesting!
Can you gibe us details who you managed to crack that? (e.g. number of cores; CPU years, etc...)

Details not out yet. The factorization

I fixed a broken link.

It is good news that cado is capable of such factorizations.

Thanks for the fix :-)


Good news indeed. Like others, I await details on wall clock time, & how many clients/nodes were involved, etc.

P.S. I'm currently factoring RSA200 using one of the git development builds, mainly to find out just how robust this particular build is in factoring such a rather large job. After nearly 5 months, there are presently 653M relations produced, ( including about 200M of oversieving ) with about 11M to go.

Eventually, I anticipate a successful factorized outcome using the stock parameter files.
