Introduction

Encryption is the backbone of secure communication. Course Plus’s Cryptography For Cyber Security course introduces you to encryption methods that protect data. This focused online class explains concepts from basic ciphers to modern cryptographic protocols. The writing is clear and engaging, using everyday examples (like coded messages) before advancing to algorithms. You will learn why encryption is vital: it “helps protect private information, sensitive data, and can enhance the security of communication”.
The course starts with classical ciphers (Caesar, Vigenère) to illustrate principles. Then you move to digital cryptography: symmetric vs asymmetric encryption, hashing and public key infrastructure. Each concept is illustrated. For example, we demonstrate how two users can exchange secret keys using Diffie-Hellman, or how RSA secures online shopping. The hands-on labs let you use encryption tools and even write simple code to encrypt text.

Course Structure

Modules include Encryption Fundamentals, Network Security Protocols (SSL/TLS), and Cryptanalysis (breaking codes). Interactive quizzes ensure you understand. A highlight is a lab where you set up your own HTTPS server certificate. We also touch on emerging topics like quantum encryption and blockchain’s cryptography. Real-world case studies (e.g., past data breaches due to poor encryption) show the stakes. After completing, you will be able to implement encryption solutions and explain their importance to colleagues. This knowledge is in global demand: companies around the world rely on professionals who understand data protection. In fact, cryptography is one of the fastest-growing fields in IT security. By finishing this course, you earn a certificate that demonstrates your skills to employers.
