Hi Salvatore, > Implement Diffie-Hellman primitives required by the scheme under the > akcipher API. Here is how it works. > 1) Call set_pub_key() by passing DH parameters (p,g) in PKCS3 format > 2) Call set_priv_key() to set your own private key (xa) in raw format > 3) Call decrypt() without passing any data as input to get back the > public part which will be computed as g^xa mod p > 4) Call encrypt() by passing the counter part public key (yb) in raw format > as input to get back the shared secret calculated as zz = yb^xa mod p I am still not convinced that akcipher is good match for key exchange methods. I think we should try to introduce a new abstraction here. Overloading set_pub_key() with DH params and using decrypt() for private/public key pair generation seems not a good fit. It does not really match. And as I said before, we know for certain that ECDH has to happen as well. So we need to forward look into making that fit as well.
