Asymmetric Key Cryptography

Discover asymmetric encryption and how it can be used to communicate without a shared key.

  • Duration

    2 weeks
  • Weekly study

    10 hours

Explore the principles of asymmetric key cryptography

Cryptography provides more than just secure communication. It also gives us ways to identify a sender or receiver, prove authorship or verify a source of information.

In this course we will see how asymmetric encryption is fundamental to modern communications and learn about the algorithms that make it possible.

What topics will you cover?

  • Asymmetric key cryptography
  • Key exchange
  • Public key infrastructure
  • RSA
  • Certificates
