About this tag
Post-quantum cryptography is a central topic on WindowsForum.com, with recent threads covering Microsoft's Quantum Safe Program and its 2029 transition target for products and services, as well as the US federal deadline for agencies to adopt quantum-resistant cryptography by 2030. Windows administrators will find practical details on enabling hybrid ML-KEM TLS 1.3 key exchange in Windows 11 and Windows Server 2025 via updates like KB5101650, and on Microsoft's SymCrypt library gaining verified Rust implementations of SHA-3 and ML-KEM. The tag also covers enterprise migration planning, including SAP's hybrid post-quantum key exchange and OpenSSH 10.4's experimental post-quantum signatures, alongside broader guidance on preparing for the shift from current public-key cryptography.

    GitHub SSH Brownout Nov. 4 Blocks SHA-1 ssh-rsa and DH KEX

    GitHub will stop accepting SHA-1-based RSA signatures (ssh-rsa) and the diffie-hellman-group-exchange-sha256 key exchange for Git over SSH. It will also require RSA keys uploaded after October 14, 2026 to be at least 3,072 bits, and it will add the post-quantum mlkem768x25519-sha256 key exchange...

    ML-DSA Certificates Add 7–10KB to TLS and QUIC Handshakes

    The post-quantum migration has moved beyond an argument about whether enterprises should prepare. It is now a systems-design problem: organizations that simply swap today’s elliptic-curve signatures for ML-DSA certificates risk making new TLS and QUIC connections slower on the networks where...
