The list of possible SSL ciphers (empty for non-SSL connections). If MySQL supports TLSv1.3, the value includes the possible TLSv1.3 ciphersuites. See Section 6.3.2, “Encrypted Connection TLS Protocols and Ciphers” . The number of SSL connection attempts to an SSL-enabled replication source server. The number of negotiates needed to establish the connection to an SSL-enabled replication source server. The SSL context verification depth (how many certificates in the chain are tested). The SSL context verification mode. The default SSL timeout. The number of successful SSL connections to the server.
