.\" Automatically generated by Pandoc 3.5 .\" .TH "mysql_get_ssl_cipher" "3" "" "Version 3.3" "MariaDB Connector/C" .SS Name mysql_get_ssl_cipher \- returns the cipher suite in use .SS Synopsis .IP .EX #include \f[B]<mysql.h>\f[R] const char *mysql_get_ssl_cipher(MYSQL *mysql) .EE .SS Description 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[CR]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[CR]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[CR]TLS_RSA_WITH_AES_128_CBC_SHA\f[R]) has different names: \f[CR]AES128\-SHA\f[R] for OpenSSL and Schannel and \f[CR]TLS_RSA_AES_128_CBC_SHA1\f[R] for GnuTLS. .SS Return value Returns a zero terminated string containing the cipher suite used for a secure connection, or \f[CR]NULL\f[R] if connection doesn\[cq]t use TLS/SSL. .SS See also .IP \[bu] 2 \f[B]mysql_ssl_set(3)\f[R]
