Yeah, I haven't seen those results either. > As I mentioned in previous meetings I believe that such a record layer > simplification would be quite useful for environments where link layer > technologies provide very small MTU sizes. AFAIK, one can save 3 bytes from the header for encrypted records in TLS 1.3. Won't go well with SRTP mux tho. (2 octet encoding for such record headers: +-+---------------+ |1|Length(15 bits)| +-+---------------+ These won't overlap with other TLS 1.3 records, as all others always have MSB of first octet clear). -Ilari _______________________________________________ TLS mailing list [email protected] https://www.ietf.org/mailman/listinfo/tls
