As far as I can see, the original text is correct, which is easy to see if you look at the corresponding paragraph of RFC 4347 (DTLS 1.0): version The version of the protocol being employed. This document describes DTLS Version 1.0, which uses the version { 254, 255 }. The version value of 254.255 is the 1's complement of DTLS Version 1.0. If the suggested text had been correct, then the encoding in RFC 4347 would have been { 254, 254 } as DTLS 1.0 is based on TLS 1.1. -- Henrik Grubbström gru...@grubba.org Roxen Internet Software AB gru...@roxen.com _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
