The writing of a text in English is satisfied with a replacement character by character. Example: STANDARD s'écrit. The numbers 0-9 are not intended to be translated into the Standard Galactic Alphabet.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 Shift (or Caesar) Cipher is another monoalphabetic substitution cipher. Although more secure than the Atbash Cipher, it is still an easy cipher to break, especially by …Well, one way is to use more than one alphabet, switching between them systematically. This type of cipher is called a polyalphabetic substitution cipher ("poly" is the Greek root for "many"). The difference, as you will see, is that frequency analysis no longer works the same way to break these. One such cipher is the famous Vigenere cipher ...The Masonic Cipher is a geometric simple substitution cipher, which exchanges letters for symbols to create encrypted messages and consists of a 26-character key which replaces every character in the alphabet with a different symbol. In history, it’s been referred to as the Pigpen Cipher, Masonic Cipher, Freemason’s Cipher, Napoleon Cipher ... It is a digraphic substitution cipher, and uses four grids to match the digraphs from plaintext to ciphertext and vice versa. Two of the grids are the plaintext grids which are just grids with the alphabet in order (combining "i" and "j" to get 25 letters), and the other two grids are Mixed Squares, each using a different keyword.
