Hi, I have a private key from an external source consisting out of moudulus n, public exponent e and private exponent d. For decrypting a message which is encrypted with the corresponding public key (n,e) I don't need the prime factors p and q. In crypto++ version 3.2 and 4.0 I could not find an interface in the class InvertibelRSAFunction and InvertibleTrapdoorFunction to setup the private key (n,d) and do a raw decryption. The only way to do this is with modular integer arithmetic. Is that correct ? Is there a reason why the RSA classes cannot be used with the private key in the form of (n,d) ?
