+
+const char *mysql_get_ssl_cipher(MYSQL *mysql)
+\f[R]
+.fi
+.SS Description
+.PP
+Returns the name of the currently used cipher suite of the secure
+connection, or NULL for non TLS connections.
+.SS Parameter
+.IP \[bu] 2
+\f[C]mysql\f[R] \- a connection identifier, which was previously
+allocated by \f[B]mysql_init(3)\f[R] and connected by
+\f[B]mysql_real_connect(3)\f[R].
+.SS Notes
+.IP \[bu] 2
+For using \f[C]mysql_get_ssl_cipher()\f[R] MariaDB Connector/C must be
+built with TLS/SSL support, otherwise the function will return NULL.
+.IP \[bu] 2
+\[ga]mysql_get_ssl_cipher()\[cq] can be used to determine if the client
+server connection is secure.
+.IP \[bu] 2
+Depending on the TLS library in use (OpenSSL, GnuTLS or Windows
+Schannel) the name of the cipher suites may differ.
+For example the cipher suite 0x002F
+(\f[C]TLS_RSA_WITH_AES_128_CBC_SHA\f[R]) has different names:
+\f[C]AES128\-SHA\f[R] for OpenSSL and Schannel and
+\f[C]TLS_RSA_AES_128_CBC_SHA1\f[R] for GnuTLS.
+.SS Return value
+.PP
+Returns a zero terminated string containing the cipher suite used for a
+secure connection, or \f[C]NULL\f[R] if connection doesn\[cq]t use
+TLS/SSL.
