Which implementation and which use case do you mean? If you are using an
external crypto library, like libcrypto from OpenSSL, DH functionality
would be coming from there for TLS. If you are talking about the
internal TLS implementation (or WPS for that matter), the internal DH
implementation would be used.

As far as the external DH implementation is concerned, this would be a
question for the crypto library. As far as the internal one is
concerned, I haven't checked the details, but I would be surprised if it
met all the requirements from SP 800-56a.
