The status variables listed on this page are all related to encrypting data during transfer with the Transport Layer Security (TLS) protocol. The term SSL (Secure Sockets Layer) is often used interchangeably with TLS, although strictly-speaking the SSL protocol is a predecessor, and is no longer considered secure. The variables listed below still use the ssl prefix for compatibility reasons, although MariaDB only supports its secure successors. See Secure Connections Overview for more.
