This is the image that was posted: My first thought was that it used steganography to hide a message, and since it was a JPEG image I tried using stegdetect by Niels Provos in case one of the detectable schemes was used.
A shift cipher replaces each letter in the plaintext with a letter or in this case, arbitrary ASCII character with a letter a certain number of positions down the alphabet. To decipher this, a perl oneliner is enough: It seems like the challenge is a bit harder than a caesar cipher after all.
Incidentally, OutGuess is also developed by Niels Provos and is available for download from the same site as stegdetect http: Unfortunately, it seems like stegdetect is only able to detect when the older OutGuess 0.
