RSA Key Generation
@param prng An active PRNG state
@param wprng The index of the PRNG desired
@param size The size of the modulus (key size) desired (octets)
@param e The "e" value (public key). e==65537 is a good choice
@param key out Destination of a newly created private key pair
@return CRYPT_OK if successful, upon error all allocated ram is freed
