What will I learn?

This Number Theory Course gives you a focused path from divisibility and modular arithmetic to RSA-style encryption with clear, rigorous proofs and hands-on computations. You will work through primes, Euler’s totient, Euler’s theorem, key generation, encryption and decryption, security principles, and best practices, then learn to present precise calculations and results in a polished final report.

Elevify advantages

Develop skills

  • Modular arithmetic mastery: apply congruences, inverses, and residue systems fast.
  • RSA key math: compute φ(n), d, and secure exponents with Euclidean algorithms.
  • Prime and totient skills: use φ(n), λ(n), and primality tests in real cryptography.
  • Encryption workflow: execute RSA encoding, modular exponentiation, and decryption.
  • Proof-writing polish: present clean number-theoretic arguments for crypto reports.
