Experiment with post-quantum cryptography today


Practically all data sent over the Internet today is at risk in the future if a sufficiently large and stable quantum computer is created. Anyone who captures data now could decrypt it.
Luckily, there is a solution: we can switch to so-called post-quantum (PQ) cryptography, which is designed to be secure against attacks of quantum computers. After a six-year worldwide selection process, in July 2022, NIST announced they will standardize Kyber, a post-quantum key agreement scheme. The standard will be ready in 2024, but we want to help drive the adoption of post-quantum cryptography.
Today we have added support for the X25519Kyber512Draft00 and X25519Kyber768Draft00 hybrid post-quantum key agreements to a number of test domains, including pq.cloudflareresearch.com.
Do you want to experiment with post-quantum on your test website for free? Mail [email protected] to enroll your test website, but read the fine-print below.
What does it mean to enable post-quantum on your website?
If you enroll your website to the post-quantum beta, we will add support for these two extra key agreements alongside the existing classical encryption schemes such as X25519. If your browser doesn’t support these post-quantum key agreements (and none at the time Continue reading
