2026 post-quantum cryptography guide updates migration advice
What happened
On October 12, Hacker News reported on a practical guide to post-quantum cryptography. The article says the post-quantum migration timeline moved up sharply in early 2026, that the industry consensus is to finish migrating by 2029, and that recommended schemes for asymmetric cryptography have therefore changed from 2018 and even from 2024. The guide recommends X25519+ML-KEM-768 for key exchange, HPKE (X-Wing) for asymmetric encryption and ML-DSA-44 for asymmetric signatures; symmetric ciphers stay largely unchanged because Grover's algorithm has limited impact. The article also lists "use the strongest model you can afford for code review" as cryptography practice advice for the first time.

后量子迁移时间线在 2026 年初大幅提前，业界共识是须在 2029 年前完成，因此所有非对称密码答案相比 2018 年乃至 2024 年都已改变。新推荐包括密钥交换用 X25519+ML-KEM-768、非对称加密用 HPKE（X-Wing）、非对称签名用 ML-DSA-44，对称密码则因 Grover 算法影响有限而基本不变。文章还首次把"用能负担的最强模型做代码审查"列为密码学正确答案。
