Look inside

You’re the new head of IT at The Fright Stuff, a small Halloween store, and it’s up to you to prevent a scary security breach! To ensure your customers’ sensitive data is secure, you’ll build an RSA public key encryption program. Along the way, you’ll learn interesting mathematical techniques such as calculating greatest common divisors and least common multiples, performing fast exponentiation, building a sieve of Eratosthenes, testing for primality, and other vital encryption skills. When you’re done, your customers’ data will be safer than ever before, and you’ll have learned essential skills for RSA encryption.

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

book resources

When you start your liveProject, you get full access to the following books for 90 days.

project author

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.

prerequisites

This liveProject is for Go programmers, from beginning level to advanced, who want to learn how to build an RSA encryption algorithm. To begin these liveProjects you’ll need to be familiar with the following:

TOOLS

  • A Go compiler (such as Visual Studio Code or Online GDB)
TECHNIQUES
  • Basic math
  • Basic Go features (including arrays, structs, and slices)

you will learn

In this liveProject, you’ll learn how RSA encryption algorithms work and the skills to build them, including:

  • Randomization
  • Calculating GCD and LCM
  • Fast exponentiation
  • Working with prime numbers
  • Factoring
  • Primality testing
