Microsoft Bolsters Windows with Quantum-Resistant Encryption
Updated May 31, 2025
Microsoft is proactively updating Windows 11 with new encryption algorithms designed to withstand potential attacks from quantum computers. This move anticipates a significant technological shift, as quantum computing promises unprecedented advancements across various fields.
While fully functional quantum computers remain in advancement, their theoretical capabilities are well-established. Unlike traditional computers that process data as bits representing 0 or 1,quantum computers use qubits. Qubits leverage quantum mechanics to exist in multiple states simultaneously, potentially revolutionizing metallurgy, chemistry, drug discovery, and financial modeling.
Averting a Cryptographic Crisis
One major implication of quantum computing is its ability to break widely used encryption methods, including the RSA cryptosystem and elliptic curve cryptography. These systems are fundamental to securing sensitive data for banks, governments, and online services globally. While current computers would take millions of years to crack RSA and elliptic curve encryption keys, a quantum computer could achieve this in mere hours.
At the BUILD 2025 conference, Microsoft announced the integration of quantum-resistant algorithms into SymCrypt, Windows’ core cryptographic library. This update is available in Windows 11 Build 27852 and later versions. Furthermore, Microsoft has updated SymCrypt-OpenSSL, its open-source project, enabling the widely adopted OpenSSL library to utilize SymCrypt for cryptographic operations.
What’s next
The move to integrate quantum-resistant encryption is expected to continue, with further updates and integrations across Microsoft products and services as the threat landscape evolves.
