Project: Caesar Cipher

This project implements a simple HTTP server that provides functionality for encrypting and decrypting text using the Caesar cipher.

Main Files

1. main.c: Implementation of the HTTP server that processes encryption and decryption requests.
2. caesar.c: Functions for encrypting and decrypting text.
3. caesar.h: Header file with function declarations.
4. test.py: Script for stress testing the server.

How to Run

1. Compile the server:

   mkdir build
   cd build
   cmake build ..
   make

2. Run the server:

   ./Caesar-Cipher_C

3. Test the server:

   • Encryption: http://localhost:8080/encrypt?text=Hello&shift=3
   • Decryption: http://localhost:8080/decrypt?text=Khoor&shift=3

4. Run the stress test (optional):

   python stress_test.py

Dependencies

• libmicrohttpd: For the HTTP server implementation.
• requests: For performing HTTP requests in the stress test script. Install it with:

  pip install requests

Features

• Easy integration of encryption/decryption into web applications.
• Stress testing capability to evaluate performance.
