mcrypt_module_open – Opening Encryption Algorithm and Mode Modules in PHP

The mcrypt_module_open function opens a module that corresponds to a specific encryption algorithm and mode in PHP.

It accepts four string parameters: $algorithm (the algorithm name or MCRYPT_ciphername constant), $algorithm_directory (the path to the algorithm module; if empty, the value from php.ini or libmcrypt’s compiled path is used), $mode (the mode name or MCRYPT_MODE constant such as "ecb", "cbc", "cfb", "ofb", "nofb", or "stream"), and $mode_directory (the path to the mode module; if empty, the value from php.ini or libmcrypt’s compiled path is used).

On success, the function returns a resource representing the encryption descriptor; on error it returns FALSE .
