Microsoft Accelerates Post-Quantum Cryptography Shift to 2029

Microsoft is accelerating its Quantum Safe Program to transition critical products and services to post-quantum cryptography by 2029, emphasizing crypto-agility (e.g., TLS 1.3, versioned ciphertext, and protecting trust chains) and adding PQC requirements to its Secure Future Initiative. The move follows similar commitments by Google and Cloudflare and is driven by recent research advances — including improvements to quantum algorithms and error-correction methods — that reduce the resources needed to break widely used public-key algorithms, raising concerns like “harvest now, decrypt later.”
