Study Notes
Caesar Shift Cipher
- Relying on shifting the letters of a message by an agreed number, the Caesar Shift Cipher is a method of encryption.
- A common shift number is three, which means each letter in the message is replaced by a letter three positions ahead of it in the alphabet.
- The recipient of the message can decode it by shifting the letters back by the same number, resulting in the original message.
- Named after Julius Caesar, who used this cipher to protect messages of military significance.
- Julius Caesar's specific method involved a shift of three.
