Encrypt and decrypt messages with different ciphertext alphabets, cases and strategies using cryptii online tools.The clock cipher is the name given to any type of encryption / code linking clocks (usually with hands) with letters of the alphabet. There are several ways of associating time/hours with letters, none is ideal, especially since by limiting the hours to 15-minute increments, a clock has 48 configurations for 26 letters.The Atbash Cipher is a simple form of monoalphabetic substitution cipher that uses the reverse of the alphabet as the key. To encrypt a message, the first step is to reverse the alphabet. This can be done by writing down the alphabet, A-Z or a-z, in the usual order and then writing it down again in reverse order. Then, for each letter in the plaintext message, … The key to the Pigpen Cipher is this easy to remember grid system. Letters are represented by the part of the grid they are in. The decryption process is just the reverse of the encryption process. Using the same key (the grid above), you locate the image depicted in the ciphertext, and replace it with the letter given by that part of the grid. Atbash Cipher Atbash is an ancient encryption system created in the Middle East. It was originally used in the Hebrew language.
