pigpen cipher
The pigpen cipher (sometimes referred to as the masonic cipher, Freemason's cipher, or tic-tac-toe cipher)〔Barker, p. 40〕〔Wrixon, p. 27〕 is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid. The example key shows one way the letters can be assigned to the grid.
==Security==
The use of symbols instead of letters is no impediment to cryptanalysis, and this system is identical to that of other simple monoalphabetic substitution schemes.
Due to the simplicity of the cipher, it is often included in children's books on ciphers and secret writing.〔Gardner〕
