About
About the curriculum
Quantum Defense is a free, interactive course that takes anyone from "what is encryption?" to reading the ML-KEM standard, with no paywall, no account and no hype.
Why it exists
The move to post-quantum cryptography is the largest cryptographic migration in history, and it has deadlines. Most of the material about it is either a press release or a research paper. This curriculum sits in between: honest about what's known and what isn't, precise where precision matters, and hands-on throughout, because you understand a one-time signature much better after you've forged one.
How the lessons are built
- Three levels. Foundations needs no math, Practitioner is for the people who run migrations, and Engineer goes inside the algorithms.
- Primary sources only. Dates, sizes and deadlines come from the standards bodies themselves, and every lesson lists its sources.
- Honest about uncertainty. Nobody knows when a cryptographically relevant quantum computer will exist. Lessons give published estimates with their authors, not predictions.
- Real cryptography in the demos. Hash-based demos use real SHA-256 in your browser. Toy schemes are clearly labeled as toys.
- Private by design. Interactives run locally, and your progress lives in your browser's storage. Nothing you type is sent anywhere.

About the creator
Kyeson Blake Utley created the Quantum Defense curriculum. A Texas security engineer, Kyeson came to cryptography through blockchain forensics: at SpookyGood, the firm Kyeson founded in 2020, the work was tracing stolen cryptocurrency for fraud victims, followed by a role as CTO of Justice Solutions Group.
Today Kyeson runs GhostKey Development, a Texas security engineering firm that helps companies migrate to post-quantum cryptography, build and audit cryptocurrency systems, and run full-scope penetration tests.
