Add SSL_verify_client_post_handshake() for servers to initiate PHA Add SSL_force_post_handshake_auth() for clients that don't have certificates initially configured, but use a certificate callback. Update SSL_CTX_set_verify()/SSL_set_verify() mode: * Add SSL_VERIFY_POST_HANDSHAKE to postpone client authentication until after the initial handshake. * Update SSL_VERIFY_CLIENT_ONCE now only sends out one CertRequest regardless of when the certificate authentication takes place; either initial handshake, re-negotiation, or post-handshake authentication. Add 'RequestPostHandshake' and 'RequirePostHandshake' SSL_CONF options that add the SSL_VERIFY_POST_HANDSHAKE to the 'Request' and 'Require' options Add support to s_client: * Enabled automatically when cert is configured * Can be forced enabled via -force_pha Add support to s_server: * Use 'c' to invoke PHA in s_server * Remove some dead code Update documentation Update unit tests: * Illegal use of PHA extension * TLSv1.3 certificate tests DTLS and TLS behave ever-so-slightly differently. So, when DTLS1.3 is implemented, it's PHA support state machine may need to be different. Add a TODO and a #error Update handshake context to deal with PHA. The handshake context for TLSv1.3 post-handshake auth is up through the ClientFinish message, plus the CertificateRequest message. Subsequent Certificate, CertificateVerify, and Finish messages are based on this handshake context (not the Certificate message per se, but it's included after the hash). KeyUpdate, NewSessionTicket, and prior Certificate Request messages are not included in post-handshake authentication. After the ClientFinished message is processed, save off the digest state for future post-handshake authentication. When post-handshake auth occurs, copy over the saved handshake context into the "main" handshake digest. This effectively discards the any KeyUpdate or NewSessionTicket messages and any prior post-handshake authentication. This, of course, assumes that the ID-22 did not mean to include any previous post-handshake authentication into the new handshake transcript. This is implied by section 4.4.1 that lists messages only up to the first ClientFinished.
