23.8.7.67 mysql_ssl_set()

my_bool mysql_ssl_set(MYSQL *mysql, const char *key, const char *cert, const char *ca, const char *capath, const char *cipher)

Description

mysql_ssl_set() is used for establishing encrypted connections using SSL. The mysql argument must be a valid connection handler. Any unused SSL arguments may be given as NULL.

If used, mysql_ssl_set() must be called before mysql_real_connect(). mysql_ssl_set() does nothing unless SSL support is enabled in the client library.

mysql_ssl_set() specifies SSL information such as certificate and key files for establishing an encrypted connection if such connections are available, but does not enforce any requirement that the connection obtained be encrypted. To require an encrypted connection, use the technique described in Section 23.8.15, “C API Encrypted Connection Support”.

Arguments:

  • mysql: The connection handler returned from mysql_init().

  • key: The path name to the key file

  • cert: The path name to the certificate file

  • ca: The path name to the certificate authority file

  • capath: The path name to a directory that contains trusted SSL CA certificates in PEM format

  • cipher: A list of permissible ciphers to use for SSL encryption

Return Values

This function always returns 0. If SSL setup is incorrect, a subsequent mysql_real_connect() call returns an error when you attempt to connect.
