Hello Shane !

Very usefull post, so I decided to download & test your AES Class.

I have an error in utf8 encode method but I don’t know how to fix it… Any idea ?

TypeError: Error #1009: Il est impossible d’accéder à la propriété ou à la méthode d’une référence d’objet nul.
at Utf8$/encode()

here’s another good read about using AES 256 bit in PHP if really needed and that AES/Rijndael 128bit are the same but with 256bit aren’t: http://kix.in/2008/07/22/aes-256-using-php-mcrypt/#comment-1371

hi, awesome post – very informative! interesting how often ports of the mentioned JS implementation are leading to the desired results.

Just shortly before I was giving up on as3crypto I got it running with following setup using PHP’s mcrypt:

AES (flash) / RIJNDAEL (php) 128bit ECB mode with a 16 characters key. Didn’t try with different settings though, after that proved to be working.
(Note that a “manual” pkcs5 unpadding is necessary in PHP to avoid garbage trailing the decrypted message: http://www.php.net/manual/en/ref.mcrypt.php#69782)

Coming to 256bit with differing key lengths I’ll be better of with your implementation I presume. Thanks!

I’m having problem with sending crypted JSON objects to AMFPHP – in random cases the crypted string contains a newline character ‘\n’ which ruins decryption on the server side. Have you ever experienced that? Any ideas how to fix it?

Sure you can, it all depends on what you need to accomplish on the server-side if decryption is necessary.

Why shouldn’t we encrypt/decrypt data with AES on client side only, do not care about PHP or server side? So we will have data encrypted not only on the fly but also in the database.
