Spotlight on an Unprotected AES128 White-box Implementation

blog

The Doar-e team posted something about unprotected AES 128 whitebox, I haven’t had time to read it yet (and it’s pretty long!) but I got quoted in the last words so here’s my repost :)

And they have linked to my not complete implementation of a DES whitebox

In the article there is an awesome explanation of AES made in flash. And it’s really really really really well made:
