Does MySQL 5.4 have native support for SSL?
Most 5.4 binaries have support for SSL connections between the client and server. We can’t currently build with the new YaSSL library everywhere, as it is still quite new and does not compile on all platforms yet. See Section 5.5.7, “Using SSL for Secure Connections”. You can also tunnel a connection via SSH, if (for instance) if the client application doesn’t support SSL connections. For an example, see Section 5.5.8, “Connecting to MySQL Remotely from Windows with SSH”.
