comment Can I crack an AES string if I have all these parameters?
@Matthew ... and verify that the result is correct by doing statistical analysis. Remember that AES decryption with incorrect keys just gets you a bunch of incorrect plaintext bytes.

This makes sense. I think malleable was the term I was originally trying to think of to describe this property.
