Caesar Cipher

The Caesar Cipher is a simple encryption technique that involves shifting each letter in a message by a fixed number of positions down the alphabet. For example, if the shift is 3, the letter A would be replaced by D, B by E, and so on. This technique is named after Julius Caesar, who allegedly used it to communicate secretly with his officials. Although it is easy to implement, the Caesar Cipher is not secure and can be easily cracked by someone who knows the shift value or uses frequency analysis
