A Caesar cipher is one of the simplest and most well-known encryption techniques.
Named after Julius Caesar, it is one of the oldest types of ciphers and is based on the simplest monoalphabetic cipher. It is considered a weak method of cryptography, as it is easy to decode the message owing to its minimum security techniques.
For the same reason, a Caesar cipher is often incorporated only in parts of other complex encryption schemes.
In cryptography, a Caesar cipher is categorized as a substitution cipher in which the alphabet in the plain text is shifted by a fixed number down the alphabet.
Advantages of using a Caesar cipher include:
Disadvantages of using a Caesar cipher include:
