Title: Remove unecessary Diffie-Hellman private key generation.

Diffie-Hellman private key, which is distinct from the **MAC key**, doesn't need to be 160 or 256-bit long, according to [specs](http://openid.net/specs/openid-authentication-2_0.html#dh_sessions). Thus setting the private key manually does not provide extra security than generate it automatically.
