php side, 1st line of init() should be:

$this->key = ($this->key != “”) ? $this->key : “”;

I would like to use your script but for encrypting/decrypting an SWF file then load it using the loader class, is this possible? or it only works for string based encrypting/decrypting .. if possible would you please show me a way?

thank you

I think I may have spotted a bug in php Crypt :: decrypt method. The thing is, if a string is padded with spaces (e.g., 11 characters are needed to pad the value), then the padding gets effectively removed by the rtrim call.
I believe, that rtrim might actually not be needed — AS3 Crypto PKCS#5 unpad implementation does not perform any trimming.

Would be really interested in a complete working AES version of this system with all the bugs removed. I was quite shocked to find out how much time I’ve had to spend finding a system to crypt data between php and actionscript. Yet still haven’t found a strong secure way.

I noticed some problems as well, but it’s not on the PHP end. Rather when decrypting on the PHP end I’m getting random chars appended to the front. I put a temporary solution that makes it work for me, but I’m not sure if it’s the right way to go because I don’t know the full extent of the problem. And it’s just a half-assed fix anyway.

if (strspn($text, chr($pad), strlen($text) – $pad) != $pad) return $text; //<– return $text instead of false when there is nothign to unpad
blockquote>

it seems that I have problem with Pading also… I submit the bug in as3Crypto their issues tab #28 but will you please explain a bit more about what you’re doing above? Thanks.

I notice the decryption is not working sometimes. I went inside and found the root of the problem.

For function pkcs5_unpad, this modification will ensure that decryption still goes through if there is no need for unpadding.

if (strspn($text, chr($pad), strlen($text) – $pad) != $pad) return $text; //<– return $text instead of false when there is nothign to unpad

It works for me but I am not a crypto artist so I am not exactly sure if this is the way to go.

Comment and keep me with the game ppl. =)
