Hands-on Cryptography

This lesson provides the student with some hands-on experience with cryptography using online tools to solve simple cryptographic problems.  It also exposes the student to techniques for encrypting and decrypting files on a Linux system.

For this lesson, we assume the instructor has provisioned accounts for his or her students in the Virginia Cyber Range and has added the Cyber Basics – Introduction to Cryptography Lab to their course. The instructor should have copies of the lab hand-out from the courseware repository.

Learning Objectives
  • Use online tools to solve simple cryptographic problems
  • Apply techniques for encrypting and decrypting files on a Linux system using both symmetric and asymmetric encryption tools
