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 designed for learning purposes and is not a complete, production-ready application or solution.

Rod Stephens

Rod Stephens started out as a mathematician but discovered the fun of algorithms and has been programming ever since. Rod was a Microsoft Visual Basic Most Valuable Professional (MVP) for 15 years, has spoken to user groups and conferences, and has taught introductory programming courses. He has written more than 35 books including Essential Algorithms: A Practical Approach to Computer Algorithms Using Python and C# and Beginning Software Engineering, both of which include material related to this series of liveProjects.


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.

  • Intermediate Rust
  • Basics of number theory and modular arithmetic
