We’ve been having issues getting a successful SSL connection from a client app trying to connect using wininet on windows xp sp3 (ie v6). The client hello looks off to me, why would the hello state its version as SSL 2.0 and then state the handshake version as SSL 3.0? Is there something coded incorrectly from the app using wininet?

    SSLv3 and TLSv1.x have a compatibility mode in case the client also supports v2 servers, as described in the TLS specification (Backward Compatibility With SSL).

    Some clients support this. For example Oracle/Sun Java has an SSLv2Hello pseudo-protocol, which uses SSLv2 Hello, but doesn’t actually support SSLv2.
