<p>Here is an example of the string transformations in use:</p>
<h2>opensips.cfg specifics</h2>
<pre><code>modparam("cfgutils", "varset", "secret=s:90hf230fh209fh209")
route {
...
xlog("L_INFO", "Call-ID : $ci\n");
$var(xor) = $(ci{s.xor, $var(secret)});
xlog("L_INFO", "Call-ID XOR : $var(xor)\n");
$var(b64encoded) = $(var(xor){s.b64encode});
xlog("L_INFO", "Call-ID b64encoded : $var(b64encoded)\n");
$var(b64decoded) = $(var(b64encoded){s.b64decode});
xlog("L_INFO", "Call-ID b64decoded : $var(b64decoded)\n");
xlog("L_INFO", "Call-ID XOR : $(var(b64decoded){s.xor, $var(secret)})\n");
}
</code></pre>
