Build Systems That Can Change Algorithms
The PQC migration will not be the last cryptographic transition. Cryptographic agility, the ability to change algorithms without major re-engineering, is what makes the next transition affordable. But agility is widely claimed and rarely achieved. This course teaches the architecture patterns that genuinely deliver cryptographic agility, how to distinguish them from patterns that only appear agile, and how to test whether a system can actually switch algorithms under realistic conditions.
Course Outline
Module 1. What Cryptographic Agility Means
Defining cryptographic agility precisely. The difference between configurable and agile. Why most systems claimed to be agile are not. The cost of inagility: why the current migration is so expensive. Agility as a design property versus a bolt-on feature.
Module 2. Agility Architecture Patterns
Architecture patterns that achieve agility. Abstraction layers for cryptographic operations. Algorithm negotiation at the protocol layer. Configuration-driven algorithm selection. Provider patterns and cryptographic service interfaces. Anti-patterns that defeat agility.
Module 3. Implementing Agility
Implementing agility at the application, protocol, and infrastructure layers. Retrofitting agility into existing systems. Key management for agile systems. Handling algorithm-specific differences (key sizes, signature sizes, performance) behind an agile interface.
Module 4. Testing, Standards, and Compliance
Testing cryptographic agility: verifying that a system can actually switch algorithms. Standards for cryptographic agility. Compliance frameworks that require agility. Building agility verification into ongoing assurance. The relationship between agility and future migration readiness.
Format and Delivery
This program is available online on-demand, live online, in person, and as private team training; current prices for each format are in the booking section below. The course runs approximately four hours. Live online and in-person sessions include 180 days of access to the online on-demand course. Where that course is not yet published, the 180 days start on the day it is.
Corporate delivery – Custom in-person or online delivery for teams. Contact training@quantumacademy.com.
Prerequisites
A working understanding of PQC fundamentals is recommended. Consider Post-Quantum Foundation or PQCS certification for background. Some courses assume security engineering experience.
Certificate of Completion
Upon completion, you will receive a Quantum Academy certificate of completion. CPE credits earned may apply toward Quantum Academy certification maintenance.
Who this course is for
Security architects, principal engineers, and technical leads who will design the systems that have to keep working through the next algorithm change as well as this one. It suits anyone whose remit is the target state rather than the current migration.
If you need to execute a migration now rather than design for the one after it, PQC Migration: Executing the Waves is the more useful course.
What you’ll be able to do afterward
- Design a system so the next algorithm change is a configuration exercise rather than a re-engineering program
- Tell apart architecture patterns that achieve agility from patterns that only claim it
- Place abstraction layers for cryptographic operations at the protocol and application layers
- Build testing that proves an algorithm swap works before you need it to
- Write agility requirements into standards, procurement, and compliance obligations
What you leave with
You leave with the course handbook, a PDF of the full material with the instructor notes written out in place of the slides’ bullet points, and a PDF copy of Quantum Ready, included at no extra cost. The handbook is yours to keep. For most organizations, that shared reference is the clearest return on a training budget.
Enrollment includes 180 days of access to the online on-demand course. Where that course is not yet published, the 180 days start on the day it is.
Where this course fits
Post-Quantum Foundation or PQCS Specialist Training give the grounding this course builds on. Neither is enforced. Hybrid Cryptographic Implementations for the implementation layer, and PQCA Architect Training for the credential.
Why we teach this
The course is built on the Applied Quantum PQC Migration Framework, published openly under Creative Commons at pqcframework.org and written by the practitioners who teach here. The people who teach this course are running migration programs inside organizations now, and the course covers what those programs hit.
