With the clock ticking on federal deadlines for Quantum-Resistant Cryptography (QRC) adoption, U.S. agencies are deep in the planning stages of a monumental cryptographic transition. While the focus is often on selecting the right quantum-resistant algorithms, the unexpected downfall of the HAWK signature scheme reveals a more fundamental requirement for a successful migration. True security in the post-quantum era will not come from a single, perfect algorithm, but from the ability to rapidly swap, update and deploy cryptographic primitives as the landscape evolves. This “crypto agility” is no longer a theoretical nice-to-have; it’s the core principle that will…
