Beschreibung

string mcrypt_cfb ( int $cipher , string $key , string $data , int $mode , string $iv )
string mcrypt_cfb ( string $cipher , string $key , string $data , int $mode [, string $iv ] )

The first prototype is when linked against libmcrypt 2.2.x, the second when linked against libmcrypt 2.4.x or higher. The mode should be either MCRYPT_ENCRYPT or MCRYPT_DECRYPT. This function should not be used anymore, see mcrypt_generic() and mdecrypt_generic() for replacements.
