Caesar Cipher

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:

• One of the easiest methods to use in cryptography and can provide minimum security to the information
• Use of only a short key in the entire process
• One of the best methods to use if the system cannot use any complicated coding techniques
• Requires few computing resources

Disadvantages of using a Caesar cipher include:

• Simple structure usage
• Can only provide minimum security to the information
• Frequency of the letter pattern provides a big clue in deciphering the entire message
