.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.
