This encryption cipher is the Caesar cipher. It is a type of substitution cipher in which each letter in the plaintext is shifted a certain number of places down or up the alphabet. It is named after Julius Caesar, who is said to have used this cipher to communicate with his generals. The Caesar cipher is a simple and easily breakable encryption method, as there are only 25 possible keys to try. **

A cipher is a method of encoding a message to make it unreadable to anyone who does not have the key to decode it. It works by substituting or rearranging the letters in the original message according to a specific algorithm or key. The recipient of the encoded message can then use the key to reverse the process and decode the message back to its original form. Ciphers have been used throughout history to protect sensitive information and are still used today in various forms of cryptography. **

The cipher number works by shifting each letter in the alphabet a certain number of spaces. For example, if the cipher number is 3, then A becomes D, B becomes E, and so on. This creates a new alphabet where each letter is shifted by the specified number. When encrypting a message, each letter is replaced with its corresponding shifted letter, and when decrypting a message, the process is reversed to reveal the original message. **
