Defeating AES Without a PhD

When I tell a developer that I broke their cryptosystem, there’s usually a pregnant pause in the conversation where they take it in, like a young child being shown a magic trick. As the initial wonder passes, though, they are not usually elated.

“I thought AES was safe. What should I use instead?”

Sorry, but AES isn’t the issue. AES, despite its very minor known flaws, isn’t considered unsafe as of this writing. 6-inch thick steel walls are difficult to break through, but that’s not generally how you get past steel walls. One goes around, under, above them, not through.

Interesting little piece on decrypting what appears to be a well encrypted parameter. If you're a web developer who's passing encrypted data around through parameters, take note of the post-mortem section.
