For example the cipher suite 0x002F (\f[C]TLS_RSA_WITH_AES_128_CBC_SHA\f[R]) has different names: \f[C]AES128\-SHA\f[R] for OpenSSL and Schannel and \f[C]TLS_RSA_AES_128_CBC_SHA1\f[R] for GnuTLS. .SS Return value .PP Returns a zero terminated string containing the cipher suite used for a secure connection, or \f[C]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]
