Yes, that was my thinking. I expect that if a certificate is sent, then it might have to be checked. As opposed to the roots, which are rarely sent or checked. Maybe it would help if Victor could describe the situation in which he thinks that it would be appropriate to send a certificate that is signed by MD5. _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
