# 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().
