I've been adding a few log lines to my code and I found where I have the
problem.
I'm generating a lot of key pairs aprox. 2.000.000 (with less key pairs 1K,
10K or 100K no problem occurs) my program close trying create a public key
after initialize the private key:
privateKey.Initialize(rng, params);
privateKey.MakePublicKey(publicKey); // <<- Here my program raise an
'Unhandled Exception' and died
My question is could be my problem that the previously created private key
is bad? Adding a validation of the private key before create the public key
could I detect the problem?
I'm creating keys using my program, no external keys are loaded so could I
validate the keys in level 0? Is enough to detect the problem? I detected
that level 2 or 3 is very slow to my volume of keys.
Once that the bad key is detected, is right try again?
Thank you very much
Regards
