Introduction to Cryptography for Architects and Developers

Course Description

Cryptography: It’s what makes it possible to safely bank, shop, and work on the internet. Cryptography helps store passwords securely and even helps prevent data loss if you lose your device. This course will teach you the cryptography basics you need to know to design and develop secure applications and systems.

Learning Objectives

  • Describe common cryptographic implementations
  • Make security-conscious decisions around cryptography
