SSL commands

SSL commands contain functions for obtaining SSL related information, such as obtaining certificates and SNI:

• SSL:cipher() — Returns the cipher in the handshake.

• SSL:version() — Returns the SSL version in the handshake.

• SSL:alg_keysize() — Returns the SSL encryption key size in the handshake.

• SSL:client_cert() — Returns the status of client-certificate-verify, whether or not it is enabled.

• SSL:sni() — Returns the SNI or false (if no SNI).

• SSL:npn() — Returns the next protocol negotiation string or false (if no NPN).

• SSL:alpn() — Allows you to get the SSL ALPN extension.

• SSL:session(t) — Allows you to get SSL session ID, reuse the session, or remove it from the cache.

• SSL:cert(t) — Allows you to get the certificate information between local or remote.

• SSL:peer_cert(str) — Returns the peer certificate in different formats.

• SSL:disable() — Disables SSL processing on either the client or server side when non-SSL traffic is expected or desired.

• SSL:cert_request() — Requests the client certificate and verifies it. This command returns Boolean true if successful, otherwise, returns Boolean false.

• SSL:get_verify_depth() — Gets the client certificate verify depth. This command returns the depth as an integer.

• SSL:renegotiate() — Requests the client side SSL renegotiation. This command returns Boolean true if successful, otherwise, returns Boolean false. Note that if renegotiation fails, this request will fail; we recommend only using this command if renegotiation is necessary.

• SSL:set_verify_depth() — Sets the client certificate verify depth. This command returns Boolean true if successful, otherwise, returns Boolean false.

• SSL:verify_result() — Gets the certificate verify result. This command returns the result as an integer.
