[Encryption] Anybody know this encryption?

[Jairo34]

Hi, my name is Jairo and i'm creating a Private server of BoomBang.tv, i created a desofuscator of it's SWF and all is OK, but the problem is the encryption of it's packets, I tried with rot-13, Base64, MD5, Sha-1 but it isn't the encryption that they use, Can you help me? Thank you, this is an example of a packet of the server:

This is a screen of the complete log of the packet because some characters aren't know with the font of ragezone...

Thank you for all Ragezoners

No problem.
First of all, you have to realize that vital data can't be MD5 or SHA1, because those are hashes, which are virtually irreversible.

I'm pretty sure thats not Base64, with all those wacky symbols.
It's bound to be a custom encryption, because public encryptions could easily be decrypted, and again hashes cannot be irreversible in some efficient way.

.. Do you have a key?
It could be AES.

yes it is AES, Thank you very much , but i haven't the key for decrypt it :S, can you help me?
