<p>The <strong>krb5_random_confounder()</strong> function creates a random
value that can be used as a confounder when encrypting data. A confounder is
used to initialize the encryption block chaining value so the encrypted result
is different each time a data value is encrypted, even when the data value and
encryption key are not changed.</p>
