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 connection, 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.
