Most systems were built with hard-coded algorithms, making changes costly and disruptive, as illustrated by the 25-year SHA-1 phase-out arc. Practical approaches to crypto-agility include building cryptographic inventories (CBOM), using abstraction layers between applications and crypto primitives, supporting algorithm negotiation in protocols, running hybrid classical/post-quantum deployments during transitions, and automating certificate lifecycle management. NIST's CSWP 39 and IR 8547 formalize these requirements, and regulations like the EU Cyber Resilience Act are making crypto-agility a compliance expectation. The core lesson: organizations that build adaptable cryptographic architectures before a migration will face far lower remediation costs than those that treat current algorithms as permanent. ## Full article daily.dev links to this article rather than hosting it.
