mysql_get_ssl_cipher(3) MariaDB Connector/C mysql_get_ssl_cipher(3)
Name
mysql_get_ssl_cipher - returns the cipher suite in use
Synopsis
#include <mysql.h>
const char *mysql_get_ssl_cipher(MYSQL *mysql)
Description
Returns the name of the currently used cipher suite of the secure con-
nection, or NULL for non TLS connections.
Parameter
• mysql - a connection identifier, which was previously allocated by
mysql_init(3) and connected by mysql_real_connect(3).
Notes
• For using mysql_get_ssl_cipher() MariaDB Connector/C must be built
with TLS/SSL support, otherwise the function will return NULL.
• `mysql_get_ssl_cipher()' can be used to determine if the client
server connection is secure.
• 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 (TLS_RSA_WITH_AES_128_CBC_SHA) has different
names: AES128-SHA for OpenSSL and Schannel and
TLS_RSA_AES_128_CBC_SHA1 for GnuTLS.
Return value
Returns a zero terminated string containing the cipher suite used for a
secure connection, or NULL if connection doesn't use TLS/SSL.
