Look inside

In this liveProject, you’ll use Rust and RSA encryption to secure the emails of your antique marble collection business. You’ll steadily build up different parts of the RSA encryption process before bringing each together in a working RSA example that can both encrypt and decrypt your email messages. Throughout the journey, you will acquire knowledge about prime number identification, factoring, probabilistic generation of random primes, and rapid exponentiation techniques.

This project is a part of the series Four Small Algorithm Projects with Rust.
This project is designed for learning purposes and is not a complete, production-ready application or solution.

prerequisites

This liveProject is for Rust programmers who want to flex their skills. You should know the basics of Rust, but you don’t need any advanced knowledge or capabilities.

TOOLS
  • Intermediate Rust
TECHNIQUES
  • Basics of number theory and modular arithmetic
