It is based on a special arrangement of letters in a grid (cross or grid like tic tac toe) in order to use 26 symbols to represent the letters of the ...Also, when you build the string, it should just be 'String.fromCharCode (13 + temp)'. I personally prefer the caesar cipher, since you can assign random shift parameters. Here's an example of how I wrote it: // s = string to encrypt, k = shift value. // s = 'SERR PBQR PNZC' and k = 13 will produce 'FREE CODE CAMP'.The atbash cipher is a simple substitution cipher from Biblical times; it reverses the alphabet such that each letter is mapped to the letter in the same position in the reverse of the alphabet (A -> Z, B -> Y). The original implementation (ca. 500 BC) was for the Hebrew alphabet and there are Old Testament references to it.Letter shifting (Caesar Cipher) Caeser Ciphers are one of the easiest ciphers to make and are really engaging in an escape party. Start by writing out the alphabet A-Z. Next write it out again underneath but shift the start to another letter like J. The amount that you move the second set of characters is called the shift or key.The Alphabet Cipher. The Alphabet Cipher (1868) by Lewis Carroll. sister projects: Wikipedia article, Wikidata item.
