‣ Pigpen Cipher is a geometrical monoalphabetic substitution cipher. It uses geometrical symbol when forming words than using the letters of the alphabet. Pigpen Cipher also known as Masonic Cipher, Napoleonic Cipher, Tic-Tac-Toe Cipher and Freemason's Cipher has been used since the 1500s.

The picture below shows the key used for encrypting and decrypting a ciphertext written in Pigpen Cipher.

Encryption:
To encode a message using Pigpen, simply find the letter you wish to encrypt and draw the lines that you see around it.

For example:

Decryption:
The decryption process is just the reverse of the encryption process. Using the same key. You need to locate the symbol depicted in the ciphertext, and replace it with the letter given by that part of the grid. The dot in the symbol will guide you to which grid you should be looking at.

For example: W has a dot inside it's symbol while S doesn't.

Ciphertext:
