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) ?
