During the BUILD 2025 conference, Microsoft revealed its plans to integrate Post-Quantum Cryptography (PQC) technology into Windows Insiders Build 27852 and subsequent versions, alongside SymCrypt-OpenSSL 1.9.0 and later releases. This strategic move aims to preemptively counter the potential disruptions posed by quantum computers to conventional encryption methods. By upgrading the "Next Generation Cryptographic Library" and enhancing "Certificate and Cryptographic Message Functionality," Microsoft equips Windows Insiders with advanced security features such as Module Lattice-based Key Encapsulation Mechanisms (ML-KEM) and Digital Signature Algorithms (ML-DSA). Notably, these algorithms constitute the inaugural batch of quantum-resistant cryptographic solutions endorsed by the National Institute of Standards and Technology (NIST). Microsoft's objective is to counteract the 'collect now, decrypt later' threat, where adversaries might amass classical encrypted data and subsequently decipher it with quantum computing capabilities. For Linux users, these algorithms are also accessible via the SymCrypt-OpenSSL library.
