11 const char *mysql_get_ssl_cipher(MYSQL *mysql)
12
13 Description
14 Returns the name of the currently used cipher suite of the secure con‐
15 nection, or NULL for non TLS connections.
16
17 Parameter
18 • mysql - a connection identifier, which was previously allocated by
19 mysql_init(3) and connected by mysql_real_connect(3).

21 Notes
22 • For using mysql_get_ssl_cipher() MariaDB Connector/C must be built
23 with TLS/SSL support, otherwise the function will return NULL.
24
25 • `mysql_get_ssl_cipher()’ can be used to determine if the client serv‐
26 er connection is secure.
27
28 • Depending on the TLS library in use (OpenSSL, GnuTLS or Windows
29 Schannel) the name of the cipher suites may differ. For example the
30 cipher suite 0x002F (TLS_RSA_WITH_AES_128_CBC_SHA) has different
31 names: AES128-SHA for OpenSSL and Schannel and
32 TLS_RSA_AES_128_CBC_SHA1 for GnuTLS.
33
34 Return value
35 Returns a zero terminated string containing the cipher suite used for a
36 secure connection, or NULL if connection doesn’t use TLS/SSL.
