We live in a moment of technological transition. What has long been theoretical, the idea that quantum computers could one day undermine the cryptographic foundations of modern systems, is quickly becoming real. The purpose of this book is to help organizations navigate that transition. Not with vague warnings or overhyped predictions, but with clear, practical guidance on what to do, when to do it, and how to do it well. This book is written for technical leaders responsible for making and sustaining long-term cryptographic decisions. That includes CISOs, security architects, PKI engineers, DevSecOps leads, and anyone responsible for the cryptographic health of an enterprise. You may already be deep into the weeds of key management and certificate lifecycle tooling. Or you may be just starting to ask whether your infrastructure will be ready when the day comes. Either way, this book is designed to meet you where you are. My goal is to turn an abstract threat into a concrete plan. Each chapter focuses on a different part of the migration journey, from discovery and inventory, through algorithm replacement and certificate renewal, all the way to ongoing maintenance and operational readiness. Along the way, we emphasize the role of crypto-agility, hybrid deployments, and shared accountability across teams. If you’re confident in your understanding of cryptography, certificates, and public key infrastructure, feel free to skip ahead. However, if you need a refresher or want to bring a colleague up to speed, the following primer provides the high-level context you require.
