But first a question, is gnutls linked in your system with libgcrypt or libnettle? The latter provides a 2x performance boost in most algorithms. Now about your selection of algorithms. Why AES-256 and not 128? If transfer speed is your only concern ARCFOUR-128 is the cipher with best performance. You may also use HMAC-MD5 instead of HMAC-SHA1 to boost speed at the cost of using a borderline algorithm. regards, Nikos _______________________________________________ Help-gnutls mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-gnutls
