Document Content and Description Below

Most primitive of cryptographic algorithms, substitutes one character of cipher text for each character of plain text. Includes Caesar Cipher Atbash Cipher Affine Cipher Rot13 Cipher ✔✔Mono-A ... lphabet Substitution First used by Julius Caesar Every letter is shifted a fixed number of spaces to the left or right the alphabet. ✔✔Caesar Cipher Hebrew Code substitutes the first letter of the alphabet for the last, and the second letter for the second to last. Simply reverses the alphabet ✔✔Atbash Cipher Each letter of the alphabet is mapped to some numeric value permuted by a simple mathematical function, and the converted back to a letter. basic formula for this cipher a = is some multiple x = represents the plain text b = is the shift M = the size of the alphabet example: ax + b (mod M) or 1x + 3 (mod 26) ✔✔Affine Cipher Single (Mono) alphabet cipher but all characters are rotated 13 characters through the alphabet.
