Caesar Cipher Encoder

Description

This project is a simple Caesar Cipher Encoder written in C. It allows users to encode messages by shifting the letters of the alphabet by a specified number of positions. Note that this implementation only supports encoding, not decoding.

Features

• Encode messages with a custom shift value
• Supports both uppercase and lowercase letters
• Ignores non-alphabetic characters

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/Caesar-Encoder.git

2. Navigate to the project directory:

   cd caesar-encoder

3. Compile the code:

   make caesar

Usage

1. Run the application:

   ./caesar key

   Replace key with the number of positions you want to shift the letters by.
2. Enter the plaintext message when prompted.
3. The encoded message will be displayed as the output.

Example

$ ./caesar 3
Plaintext: hello
ciphertext: khoor

*Can you guess what the shift is? It's 16!
