A Cryptography Engineer’s Perspective on Quantum Computing Timelines
Summary
A cryptography engineer argues that quantum computing timelines are accelerating, prompting urgent migration to post-quantum cryptography (ML-KEM/ML-DSA). The piece cites recent research and expert voices predicting a significant threat by 2029, recommends shipping PQ crypto now, and discusses implications for TLS/X.509, key exchanges, and hardware attestation, while noting symmetric crypto remains easier to defend.
