Using SSL for Secure Connections
MySQL supports secure (encrypted) connections between MariaDB clients and the server using the Secure Sockets Layer (SSL) protocol. This section discusses how to use SSL connections. For information on how to require users to use SSL connections, see the discussion of the REQUIRE clause of the GRANT statement in , "GRANT Syntax".
The standard configuration of MariaDB is intended to be as fast as possible, so encrypted connections are not used by default. For applications that require the security provided by encrypted connections, the extra computation to encrypt the data is worthwhile.
MySQL enables encryption on a per-connection basis. You can choose a normal unencrypted connection or a secure encrypted SSL connection according the requirements of individual applications.
Secure connections are based on the OpenSSL API and are available through the MariaDB C API. Replication uses the C API, so secure connections can be used between master and slave servers.
Another way to connect securely is from within an SSH connection to the MariaDB server host. For an example, see , "Connecting to MariaDB Remotely from Windows with SSH".
