rot cipher the rot cipherone of the simplest encryption algorithmsstands for "rotate spaces the cypher represents the letters to as the numbers to in such way that the encrypted letter is spaces from the plaintext lettera becomes nb becomes oand so on the encryption process is identical to the decryption processmaking it trivial to program howeverthe encryption is also trivial to break because of thisyou'll most often find rot used to conceal non-sensitive informationsuch as spoilers or trivia answersso it' not read unintentionally more information about the rot cipher can be found at wiki/rot if you' like to learn about ciphers and code breaking more generallyyou can read my book cracking codes with python (no starch press
