rsa-cryption-rust

Overview

This repository provides sample implementations of RSA encryption/decryption, digital signature, and secure server-client communication in Rust.
You can try encryption, signature, or TCP-based secure message exchange using command-line arguments.

Directory Structure

• src/rsa_cryption.rs
  RSA encryption and decryption logic (library API)
• src/rsa_signature.rs
  RSA digital signature and verification logic (library API)
• src/rsa_server_client.rs
  TCP server-client communication using RSA encryption
• src/main.rs
  Command-line interface for feature selection
• src/lib.rs
  Module definitions and documentation

Usage

1. Make sure you have Rust installed.

2. Clone this repository and navigate to the project directory.

3. Run the following commands:

   • To run the encryption/decryption demo:

     cargo run -- crypto

   • To run the signature/verification demo:

     cargo run -- signature

   • To run the server-client RSA communication:

     • Start the server in one terminal:

       cargo run -- server

     • Start the client in another terminal:

       cargo run -- client

Features

• Learn the basics of RSA cryptography in Rust
• Practice modular Rust programming
• Interactive console-based demos for encryption, digital signatures, and secure TCP communication
