mcrypt_generic_deinit
(PHP 4 >= 4.0.7, PHP 5)
mcrypt_generic_deinit — This function deinitializes an encryption module
Description
bool mcrypt_generic_deinit
( resource $td
)
This function terminates encryption specified by the encryption descriptor (td ). It clears all buffers, but does not close the module. You need to call mcrypt_module_close() yourself. (But PHP does this for you at the end of the script.) Returns FALSE on error, or TRUE on success.
See for an example mcrypt_module_open() and the entry on mcrypt_generic_init().

Ok guys, an easy one here.
What we are doing here is basically ending or concluding the encryption, clearing our buffers (what would we do without them).
Just be warned that it will not close the module. You will personally need to call the rather sensuous mcrypt_module_close() yourself. Alternatively you could just rely on PHP to do this for you at the end of the code, nature is beautiful!
