mysql_ssl_set(3) MariaDB Connector/C mysql_ssl_set(3)
Name
mysql_ssl_set - Sets TLS/SSL options
Synopsis
#include <mysql.h>
my_bool mysql_ssl_set(MYSQL *mysql,
const char *key,
const char *cert,
const char *ca,
const char *capath,
const char *cipher)
Description
Used for establishing a secure TLS connection. It must be called be-
fore attempting to use mysql_real_connect(3). TLS support must be en-
abled in the client library in order for the function to have any ef-
fect.
NULL can be used for an unused parameter. Always returns zero.
To enable TLS without specifying certificates, set all values to NULL:
mysql_ssl_set(mysql, NULL, NULL, NULL, NULL, NULL)
This is the same as mysql_optionsv(mysql, MYSQL_OPT_SSL_ENFORCE, &yes).
Parameter
• 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 certifi-
cates in PEM format.
• cipher list of permitted (SSLv3, TLSv1.0 or TLSv1.2) cipher suites to
use for TLS encryption.
Notes
• 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.
