The Caesar cipher is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet. This program allows you to encrypt and decrypt messages using the Caesar cipher.
- Encryption: You can encode plaintext messages using the Caesar cipher.
- Decryption: You can decode Caesar cipher messages to recover the original plaintext.
- Shift Value: You can specify the number of positions to shift each letter in the alphabet.
- User-Friendly: The program provides a simple command-line interface for easy interaction.
- Error Handling: The program includes basic error handling to handle invalid inputs.
