Thanks. The tutorials are very interesting. Especially I like a first tutorial with RSA breaking but I think the use of RSA Tool for a prime factorization is a very complex way.
Just a simple example. The time that should be spent for a factorization of a 256-bit RSA modulus N (from tutorial #1) 8640FF9C022F0FB3447F82C6F23CA36703741985A9E35EE670B36B6553926A9D is:
RSATool2 = 01h:18m:37s;
KeygenerAssistant = 00h:05m:53s;
msieve = 00h:04m:47s.

Does anybody use RSA Tool yet?

RSATool2 is 2006 tool https://tuts4you.com/download.php?view.455

and I think we have come a long way from then... and use new tools to do the same things :)
