You don’t need quantum hardware for post-quantum security
Post-quantum cryptography protects against quantum threats using today’s hardware. Quantum tech like QKD may sound appealing, but it isn’t necessary or sufficient to secure organizations.

Chaos in Cloudflare’s Lisbon office: securing the Internet with wave motion
Cloudflare is now using a wall of waves in our Lisbon, Portugal office to create entropy and strengthen Internet security, turning liquid chaos into secure, unpredictable encryption.
How Cloudflare and Wall Street Are Helping Encrypt the Internet Today
Today has been a big day for Cloudflare, as we became a public company on the New York Stock Exchange (NYSE: NET). To mark the occasion, we decided to bring our favorite entropy machines to the floor of the NYSE.
League of Entropy: Not All Heroes Wear Capes
Everything from cryptography to big money lottery to quantum mechanics requires some form of randomness. But what exactly does it mean for a number to be randomly generated and where does the randomness come from?
Inside the Entropy
Generating random outcomes is an essential part of everyday life; from lottery drawings and constructing competitions, to performing deep cryptographic computations.
LavaRand in Production: The Nitty-Gritty Technical Details
As some of you may know, there's a wall of lava lamps in the lobby of our San Francisco office that we use for cryptography. In this post, we’re going to explore how that works in technical detail.
Randomness 101: LavaRand in Production
As some of you may know, there's a wall of lava lamps in the lobby of our San Francisco office that we use for cryptography. In this post, we’re going to explore how that works.
Ensuring Randomness with Linux's Random Number Generator
When building secure systems, having a source of random numbers is essential. Without them, most cryptographic systems break down and the privacy and authenticity of communications between two parties can be subverted.
