Instances3Eq, Ord, Show

valuegenDHParams :: DHGen -> Int -> IO DHP

genDHParams gen n generates n-bit long DH parameters.

valuegetDHLength :: DHP -> IO Int

Get DH parameters length (in bits).

valuecheckDHParams :: DHP -> IO Bool

Check that DH parameters are coherent.

valuegenDH :: DHP -> IO DH

The first step of a key exchange. Public and private keys are generated.

valuegetDHParams :: DH -> DHP

Get parameters of a key exchange.

valuegetDHPublicKey :: DH -> IO Integer

Get the public key.

valuecomputeDHKey :: DH -> Integer -> IO ByteString

Compute the shared key using the other party's public key.
