announced that Windows 11 Canary build 27852 and higher now support post-quantum cryptography, through PQC algorithms, allegedly securing them against quantum computers’ unmatched crypto hacking power (against traditional crypto algorithms).

Specifically,

’s cryptographic library) to support ML-KEM, and ML-DSA (on top of PQC) through its Cryptography API: Next Generation libraries and certificate and cryptographic messaging functions.

ML-KEM is aimed at helping secure keys against the “harvest now, decrypt later“ threat. That’s a threat where attackers focus on collecting targeted data today, then store it and wait for quantum computers to become fast enough to break the encryption on the targeted data in the future.

ML-DSA is designed for scenarios that require verification of identity, as well as maintaining the integrity of digital signatures.

PQC (post-quantum cryptography) algorithms are designed specifically to counter attacks from quantum computers, using mathematical equations that are allegedly difficult for both classical and quantum computers to tackle. However, these algorithms are much more demanding on hardware, allegedly requiring larger key sizes, longer compute times, and more bandwidth than classical cryptography algorithms.

is preparing its entire ecosystem of Windows operating systems and other products against future attacks from quantum computers. For now, this tech is being tested in Windows 11 with the aforementioned 27852 Canary build (or newer), but PQC will also be coming to Linux in the near future.

did not say if or when BitLocker might get a PQC update, but due to its complexity and hardware demands, don’t expect it to arrive anytime soon.

Attacks from quantum computers are a real threat. Last year, ******** researchers successfully cracked military grade encryption with a D-Wave quantum computer. This attack was done as a test, but nonetheless, it shows that quantum computers already have enough computing power to crack some of the most complex classical cryptography in the world. This threat will only get more prominent in the future as quantum computers develop and go mainstream.
