Four key risks are outlined: breaking public-key encryption (RSA, ECC, Diffie-Hellman), HNDL data interception, Grover's algorithm accelerating brute-force attacks, and AI-quantum convergence amplifying vulnerability discovery. NIST's 2024 PQC standards and US/EU regulatory mandates are accelerating post-quantum migration timelines. Organizations are advised to complete cryptographic inventories by 2026, design for crypto-agility by 2028, and prioritize migration of long-lived sensitive data and identity infrastructure. Delaying preparation risks compressed timelines, higher costs, and regulatory exposure. ## Full article daily.dev links to this article rather than hosting it.
