const char *key,
const char *cert,
const char *ca,
const char *capath,
const char *cipher)


Used for establishing a secure TLS connection. It must be called before attempting to use mysql_real_connect(3). TLS support must be enabled in the client library in order for the function to have any effect.

NULL can be used for an unused parameter. Always returns zero.


mysql - a mysql handle, which was previously allocated by mysql_init(3).
key - path to the key file.
cert - path to the certificate file.
ca - path to the certificate authority file.
capath - path to the directory containing the trusted TLS CA certificates in PEM format.
cipher list of permitted (SSLv3, TLSv1.0 or TLSv1.2) cipher suites to use for TLS encryption.


mysql_real_connect(3) will return an error if attempting to connect and TLS is incorrectly set up.
Even if Connector/C supports TLSv1.3 protocol, it is not possible yet to specify TLSv1.3 cipher suites via cipher parameter.
