Did you know?
To encrypt, a table of alphabets can be used, termed a tabula recta, Vigenère square or Vigenère table. It has the alphabet written out 26 times in different rows, each alphabet shifted cyclically to the left compared to the previous alphabet, corresponding to the 26 possible Caesar ciphers. See more The Vigenère cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers, based on the letters of a keyword. It employs a form of polyalphabetic substitution. First described by See more In a Caesar cipher, each letter of the alphabet is shifted along some number of places. For example, in a Caesar cipher of shift 3, a would … See more The idea behind the Vigenère cipher, like all other polyalphabetic ciphers, is to disguise the plaintext letter frequency to interfere with a straightforward application of frequency analysis. For instance, if P is the most frequent letter in a ciphertext whose plaintext is in See more • Roger Frontenac (Nostradamus quatrain decryptor, 1950) See more The very first well-documented description of a polyalphabetic cipher was by Leon Battista Alberti around 1467 and used a metal cipher disk to switch between cipher alphabets. Alberti's … See more Vigenère can also be described algebraically. If the letters A–Z are taken to be the numbers 0–25 ($${\displaystyle A\,{\widehat {=}}\,0}$$, $${\displaystyle B\,{\widehat {=}}\,1}$$, etc.), and addition is performed modulo 26, Vigenère encryption See more Running key The running key variant of the Vigenère cipher was also considered unbreakable at one time. For the key, this version uses a block of text as long as the plaintext. Since the key is as long as the message, the Friedman and … See more WebContinue with the next letter of the plaintext, and the next letter of the key. When arrived at the end of the key, go back to the first letter of the key. Example: DCODE. KEYKE. Example: NGMNI is the ciphertext. …

WebColumnar Transposition Cipher# Columnar Transposition Cipher is a type of transposition cipher in which the plaintext is rearranged and then encrypted. In this technique, the plaintext is written in rows and then read out column by column. The order of the columns is determined by a keyword or a key phrase provided by the sender. How It Works#

The Baconian cipher, or Bacon's cipher, is a method for steganography invented by Francis Bacon in 1605. Each letter is translated into a pattern of five digits or the letters 'A' and 'B'.
