#include \f[B]<mysql.h>\f[R]

my_bool mysql_ssl_set(MYSQL *mysql,
                      const char *key,
                      const char *cert,

.SS Description
Used for establishing a secure TLS connection.
It must be called before attempting to use
\f[B]mysql_real_connect(3)\f[R].
TLS support must be enabled in the client library in order for the
function to have any effect.
.PP
\f[CR]NULL\f[R] can be used for an unused parameter.
Always returns zero.
.PP
To enable TLS without specifying certificates, set all values to
\f[CR]NULL\f[R]:
.IP
.EX
mysql_ssl_set(mysql, NULL, NULL, NULL, NULL, NULL)
.EE
.PP
This is the same as
\f[CR]mysql_optionsv(mysql, MYSQL_OPT_SSL_ENFORCE, &yes)\f[R].
.SS Parameter
.IP \[bu] 2
\f[CR]mysql\f[R] \- a mysql handle, which was previously allocated by
\f[B]mysql_init(3)\f[R].
.IP \[bu] 2
\f[CR]key\f[R] \- path to the key file.
.IP \[bu] 2
\f[CR]cert\f[R] \- path to the certificate file.
.IP \[bu] 2
\f[CR]ca\f[R] \- path to the certificate authority file.
.IP \[bu] 2
\f[CR]capath\f[R] \- path to the directory containing the trusted TLS CA
certificates in PEM format.
.IP \[bu] 2
\f[CR]cipher\f[R] list of permitted (SSLv3, TLSv1.0 or TLSv1.2) cipher
suites to use for TLS encryption.
.SS Notes
.IP \[bu] 2
\f[B]mysql_real_connect(3)\f[R] will return an error if attempting to
connect and TLS is incorrectly set up.
.IP \[bu] 2
Even if Connector/C supports TLSv1.3 protocol, it is not possible yet to
specify TLSv1.3 cipher suites via \f[CR]cipher\f[R] parameter.
