The pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram. [1]The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Rosicrucian cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.
The cipher at the foot of the gravestone says "Holiness of the Lord". The Pigpen cipher was used by Freemasons in the 18th century to keep their records private and surprisingly the cipher on Thomas Brierley's grave seems to have a non-standard symbol for the letter "S". It is possible the variation in the cipher is a clue to or a key to ...
Nyctography (in Nyctography:) is a form of substitution cipher writing created by Lewis Carroll (Charles Lutwidge Dodgson) in 1891. It is written with a nyctograph (a device invented by Carroll) and uses a system of dots and strokes all based on a dot placed in the upper left corner. Using the Nyctograph, one could quickly jot down ideas or ...

Edward Larsson's rune cipher resembling that found on the Kensington Runestone.Also includes runically unrelated blackletter writing style and pigpen cipher.. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
Traditionally the Three dots (∴) also known as "tripunctual abbreviation" or "triple dot" is a symbol used all over the world in Freemasonry for abbreviations, signatures, and symbolic representation.
The Polybius square is also used as a basic cipher called the Polybius cipher. This cipher is quite insecure by modern standards, as it is a substitution cipher with characters being substituted for pairs of digits, which is easily broken through frequency analysis. [2]
However, it has been claimed that polyalphabetic ciphers may have been developed by the Arab cryptologist Al Kindi (801–873) centuries earlier. [2] The Alberti cipher by Leon Battista Alberti around 1467 was an early polyalphabetic cipher. Alberti used a mixed alphabet to encrypt a message, but whenever he wanted to, he would switch to a ...
