A padding oracle is a "device" (or for historically correct purposes a stoned virgin trapped in an enclosure) that reports on the correctness of the padding of a piece of cipher-text. We're going to abuse this mechanism in order to decrypt some cipher-text encrypted under a block cipher in CBC mode.

Mhm, not sure about your presentation Keith. The example is quite crazy and not well backed-up by arguments...
