Alphabet cipher.

By applying a Polybius cipher encryption you shrink the set of symbols necessary to represent a message from the original alphabet (typically 26 symbols) to the set of symbols you need to denote the coordinates of each letter in the ciphertext (typically 5 symbols). This can be very useful for telegraphy, steganography, and cryptography.Shift cipher quick check tool. This is a tool to check if any ciphertext is a shift cipher by printing out all possible rotations and presenting them back. Obviously it will also convert any text you enter into its rotated equivalent. Common options are ROT13, a 13 shifted cipher, being half of the letters of the alphabet. The shift cipher is a cryptographic substitution cipher where each letter in the plaintext is replaced by a letter a certain number of positions further down the alphabet. This number of positions is sometimes called a key. The Caesar code is the most well-known shift cipher, usually presented with a shift key of value 3. Another scheme that uses a memorable key for a simple substitution cipher is called the keyword cipher. Its key is an easily memorized word or phrase. ...
