Cracking Codes: Part IV

Here are a couple more ciphers for you to mull over and add to your encryption repertoire: the ancient Masonic cipher and a variation, called the tic-tac-toe cipher, which is used to encrypt numbers instead of letters.

Masonic Cipher

The centuries old Masonic cipher uses two tic-tac-toe diagrams and two X patterns to represent the letters of the alphabet. Letters are enciphered using the patterns formed by the intersecting lines and dots.

Tic-Tac-Toe Cipher

As mentioned above, a variation of the Masonic cipher used to encrypt numbers is the tic-tac-toe cipher. Using this pattern, each number can be enciphered with the character that is formed by the intersecting lines surrounding each number. The 0 is enciphered using an X.
