Historical and Modern Cryptography for Security Professionals by Chris Lytle & Dan Crowley

Course Description

With the recent renewed debate on the necessity of privacy, cryptography is once again in the public eye. Due to the gulf between classical cryptography and mechanized modern cryptography it can be difficult to know where to start in order to get an applicable background in cryptography for the modern security professional.

In this course, we'll start with the earliest and most important ciphers and cryptographic concepts and build on that knowledge using important ciphers from across the ages until we can talk about contemporary digital cryptosystems and finally, how to attack them. Over the course of this training we'll discuss the history of how ciphers came to be, what role they played, and how they fell. We will also implement these ciphers and cryptanalyze them. Attendees should bring a VMWare enabled laptop, all other materials will be provided.


  • Build a foundation for understanding of modern cryptography based on historical cryptography
  • Provide practical experience in analyzing and breaking historical cryptography
  • Develop an understanding of modern cryptographic concepts
  • Introduce common mistakes made in modern cryptosystems and provide practical experience in exploiting them
