This method ensures that each letter in the plaintext is substituted by a different letter in the ciphertext. If any letters overlap at the end of the alphabet, such as Z-Z or X-X, they are repositioned to maintain the cipher's security and adhere to guidelines established by the American Cryptogram Association [1].
A cryptogram is a type of puzzle that consists of a short piece of encrypted text. [1] Generally the cipher used to encrypt the text is simple enough that the cryptogram can be solved by hand. Substitution ciphers where each letter is replaced by a different letter, number, or symbol are frequently used. To solve the puzzle, one must recover ...

[ 9 ] [ 10 ] In the 19th century, the personal advertisements section in newspapers would sometimes be used to exchange messages encrypted using simple cipher schemes.
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.

Alternative grilles possess apertures for single letters only and can be used quickly. Messages are filled out with a jumble of letters or numbers and are clearly cryptograms whereas Cardano intended to create steganograms. These single-letter grilles may be named after Cardano, but they are also called simply cardboard ciphers.
