(The quoting got too much for me, check archives for thread context.) The language in the TLS 1.0 and 1.1 specs is something like: > TLS versions 1.1 and 1.0, and SSL 3.0 are very similar; thus, > supporting both is easy. TLS clients who wish to negotiate with such > older servers SHOULD ... Notice the conditional SHOULD there. It seems to support the view that successful negotiation with an SSLv3 server (especially a broken one) is not considered a MUST for a conformant TLS implementation. What if we adapt the proposed language thusly: Clients that wish to be compatible with the maximum number of older servers (including SSLv3 servers not supporting TLS), SHOULD signal using the special TLS cipher suite value rather than including an extension on the initial Client Hello. (Note that this does not apply to any subsequent Client Hello messages sent.) Any such client MUST be prepared to receive in response a Server Hello message of any negotiable version (subject to the usual rules) which contains the extension. Clients are not required to offer support back to SSLv3, but if they do, they MUST implement the behaviors described in this specification. - Marsh
