What will I learn?

This Number Theory Course provides a clear path from divisibility and modular arithmetic to RSA-style encryption, with strong proofs and practical calculations. You will study primes, Euler’s totient, Euler’s theorem, key generation, encryption and decryption, security basics, and best practices, then learn to present accurate calculations and results in a neat final report.

Elevify advantages

Develop skills

  • Master modular arithmetic: use congruences, inverses, and residue systems quickly.
  • Handle RSA key calculations: find φ(n), d, and safe exponents using Euclidean methods.
  • Develop prime and totient abilities: apply φ(n), λ(n), and primality checks in actual cryptography.
  • Carry out encryption process: perform RSA encoding, modular exponentiation, and decryption.
  • Improve proof-writing: deliver clear number theory arguments for cryptography reports.

What our students say

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... I appreciate everything you do, I've already recommended you to others...

I like how the lessons are straight to the point and how I can switch chapters and skip content I don't need.
