note 34611 added to function.mcrypt-module-open

Doing a trim($decrypted) will remove the null padding that may occur as a result of decryption. The problem is if you're encrypting something like a MSWord document which can commonly end with nulls. The result $decrypted will be smaller than the original cleartext - which will then fail to open in MSOffice. To get around this, make sure you store the length of the original cleartext, and when you decrypt it, do: $decrypted = substr(mdecrypt_generic($td, $encrypted), 0, $originalLength); ---- Manual Page -- http://www.php.net/manual/en/function.mcrypt-module-open.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+34611 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+34611&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+34611&report=yes
