You used prv.txt, then priv.txt (with extra "i"). > CryptoPP::Exception caught: NullRNG: NullRNG should only be passed to functions that > don't need to generate random bytes This is a bug in the testing code. Please see http://www.mail-archive.com/[EMAIL PROTECTED]/msg00137.html > When I generate key pair, is there any requirment for key length and seed? When generating RSA keys, the only hard requirement is that key length has to be at least 16. But for security you should use at least 1024 bits. For production code, use the AutoSeededRandomPool, which does not require a seed. The test code uses a user-provided seed for bug reproducibility.
