In general yes, but note that gnutls_mac_algorithm_t is a superset of gnutls_digest_algorithm_t, i.e., a MAC algorithm may not always be a digest algorithm (e.g. UMAC). I'll try to add similar functions for the digest algorithms to avoid such issues. regards, Nikos _______________________________________________ Gnutls-help mailing list [email protected] http://lists.gnupg.org/mailman/listinfo/gnutls-help
