κρυπτοσ or kryptos, is a contest open to any and all undergraduate students. The theme of the contest is centered around the breaking, or cryptanalysis, of ciphers (secret writing). Each challenge presents contestants with a brief scenario together with some ciphertext (encoded message). The goal is to discover the original English plaintext message! Clues to help break the cipher may be contained in the actual ciphertext or in the details of the accompanying scenario.
