I'm just trying to run the test.cpp file that comes with Crypto++ 5.1 to sign a file
using RSA, using the command:
CTDebug\cryptest.exe rs key_priv.txt infile.txt sign.txt
I get the error message:
CryptoPP::Exception caught: NullRNG: NullRNG should only be passed to functions
that don't need to generate random bytes
The stack trace is:

Anyone know what the problem is?
