Comment:

 > So, are the handshakes using SSLv3, or are they not? :)

 OpenSSL prior to 1.1.0 uses `ssl3_connect()` to do the actual connection
 work, even if you are using TLS (See: `ssl/t1_clnt.c`).  OpenSSL 1.1.0 and
 later renames and refactors everything, and will display `SSLv3/TLS read
 server certificate` here instead.

 lies to us.

 Indeed.  And there's nothing we can do about it.

 {{{
   SSL_CTX_set_options(result->ctx, SSL_OP_NO_SSLv2);
   SSL_CTX_set_options(result->ctx, SSL_OP_NO_SSLv3);
 }}}

 If people are really worried, they can gather a pcap containing the
 ClientHello and look at the version while keeping in mind Appendix E of
 the RFC.

 Since this is cosmetic, OpenSSL's fault, and fixed in newer OpenSSL, I'm
 going to close this.  Reopen it once someone produces a pcap displaying
 horrifyingly wrong behavior.
