Does anyone know of something like Bitaddress.org, but for AES?

I want to be able to download it as a HTML file and put it on my offline "Bitcoin banking computer".

It should encode, decode and take input and a key (so I can encode private keys).


I am immensely inspired by the fact that SO FAR DPR has been in FBI custody for months and had had all his possessions confiscated and STILL they don't have his money.
That is so fucking powerful.

Im already safe against hacking and theft (I think) but if I could be safe from the police too...

EDIT: I found this - http://lazarsoft.info/crypter.html
And it seems to work as I want, but I can't seem to get any of the online AES tools to actually work together, they all give different results from the same key/input.
