Caesar cipher. The action of a Caesar cipher is to replace each plaintext letter with a different one a fixed number of places down the alphabet. The cipher illustrated here uses a left shift of 3, so that (for example) each occurrence of E in the plaintext becomes B in the ciphertext. In cryptography, a Caesar cipher, also known as Caesar's ...
The book's intricate design also conceals a series of hidden symbols that spell out a secret message when their code is deciphered, if the reader is clever enough to find them. Contents. Chapter I: The Work of a Wizard; Chapter II: A Wizard's Map of the World; Chapter III: The Master Wizard's Workshop; Chapter IV: A Wizard's Robes & Tools
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 example key shows one way the letters can be assigned to the grid.
Book cipher. The King James Bible, a highly available publication suitable for the book cipher. A book cipher is a cipher in which each word or letter in the plaintext of a message is replaced by some code that locates it in another text, the key . A simple version of such a cipher would use a specific book as the key, and would replace each ...
X. Y. Z. The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by-letter basis in a very simple way. The message is transmitted using a series of tap sounds, hence its name. [1] The tap code has been commonly used by prisoners to communicate with each other. The method of communicating is usually by tapping ...
Inveniam viam. " Aut inveniam viam aut faciam " (or " Aut viam inveniam aut faciam ") is Latin for "I shall either find a way or make one". [1] [2] [3] The first word " aut " may be omitted, corresponding to omitting the English word "either" from the translation. The phrase has been attributed to Hannibal; when his generals told him it was ...
The partially decomposed body of Ricky McCormick was discovered in a field in St. Charles County, Missouri on June 30, 1999. Sheriffs found two garbled hand-written notes – apparently written in secret code – in the victim's pockets, and these were handed over to the FBI for further investigation. Attempts by the FBI's Cryptanalysis and ...
Cryptography. Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized : kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [1] ), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
