Cryptography, Encryption & Digital Evidence

Dive into the thrilling intersection of computer science, law, and digital forensics with this comprehensive, no-prep curriculum unit on Cryptography and Digital Evidence. Designed for advanced high school (Grades 10-12) and early college students, this resource is the perfect turnkey solution for courses in AP Computer Science, Cybersecurity (CTE), Digital Forensics, and even tech-focused Government or Civics classes.

This isn’t just about theory; it’s about application. This rigorous module bridges the gap between the mathematical certainties of encryption and the gray areas of constitutional law. Students will move from understanding the “what” of cryptography to the “why” and “how” it’s used in real-world criminal investigations, corporate espionage, and landmark court cases like Apple v. FBI.
