Caesar cipher | PPT - SlideShare
Aug 15, 2013 · The Caesar cipher is one of the earliest known substitution ciphers. It works by shifting each letter in a plaintext message by a set number of positions (the key) in the alphabet to encrypt it. For example, with a key of 3, A would be replaced by D, B by E, and so on.
Types: Cipher : cipher is a character-for-character or bit-for-bit transformation, without regard to the linguistic structure of the message. Code : a code replaces one word with another word or symbol.
