``FC_DigestFinal`` finishes a multi-part digest operation by returning the complete digest and
clearing the operation context. If ``pDigest`` is NULL the length of the digest is returned and
``FC_DigestFinal`` may be called again with ``pDigest`` set to retrieve the digest.
A user may call ``FC_DigestFinal`` without logging into the token (to assume the NSS User role).
