classDH : KeyAgreement

Diffie-Hellman Key Agreement.

The shared-secret exponentiation blinds the private exponent with a fresh random multiple of p-1 before the (variable-time) powmod, so each call evaluates an unpredictable exponent and timing measurements cannot be averaged into the secret. This assumes the standard DH setting of a prime p.
