MySQL
By default, SSLsupport is disabled when you are building MySQL. To build MySQL
with OpenSSLsupport enabled, you must specify the --with-vio and --with-openssl
options on the command line to the configuration script. Once you have an SSLenabled
version of MySQLbuilt, installed, and running, you can verify that SSLis
supported with the following SQL command:
SHOW VARIABLES LIKE 'have_openssl'
If the result of the command is yes, SSL support is enabled.
With an SSL-enabled version of MySQL running, you can use the GRANT command to
designate SSLrequirements for accessing a particular database or table by user. Any
client can specify that it wants to connect to the server using SSL, but with the GRANT
options, it can be required.
When writing code using the MySQLC API, use the following mysql_real_connect( )
function to establish a connection to the server instead of using mysql_connect( ),
which has been deprecated. All that is actually required to establish an SSLconnection
from the client to the server is to specify the CLIENT_SSL flag to mysql_real_
connect( ).

int spc_mysql_real_connect(MYSQL *mysql, const char *host, const char *pw,
const char *db, unsigned int flags) {
int port = 0, result = 0;
char *host_copy = 0, *p;
const char *socket = 0, *user = 0;
if (host) {
if (!(host_copy = strdup(host))) return 0;
if ((p = strchr(host_copy, '@')) != 0) {
user = host_copy;
*p++ = 0;
host = p;
}
if ((p = strchr((p ? p : host_copy), ':')) != 0) {
*p++ = 0;
port = atoi(p);
}
if (*host = = '/') {
socket = host;
host = 0;
}
}
/* this bit of magic is all it takes to enable SSL connections */
flags |= CLIENT_SSL;
