This function terminates encryption specified by the encryption
descriptor (<em><code class="parameter">td</code></em>). It clears all buffers, but does
not close the module. You need to call
<span class="function"><a href="function.mcrypt-module-close.html" class="function">mcrypt_module_close()</a></span> yourself. (But PHP does this for
you at the end of the script.)
