Yes you are right.
I found a solution anyway implementing a subclass
of IteratedHashWithStaticTransform called "NoneHash" with this method
implementation to 32 bytes digest.
void NoneHash::Transform(CryptoPP::word32 *state, const CryptoPP::word32
*data)
{
state[0] = data[0];
state[1] = data[1];
state[2] = data[2];
state[3] = data[3];
state[4] = data[4];
state[5] = data[5];
state[6] = data[6];
state[7] = data[7];
}
Regards
