Today we announced Geo Key Manager, a feature that gives customers unprecedented control over where their private keys are stored when uploaded to Cloudflare. This feature builds on a previous Cloudflare innovation called Keyless SSL and a novel cryptographic access control mechanism based on both identity-based encryption and broadcast encryption.
This is a guest post by Elie Bursztein who writes about security and anti-abuse research. It was first published on his blog and has been lightly edited. This post summarizes how prevalent encrypted web traffic interception is and how it negatively affects online security according to a study published at
This blog post presents a new cryptography primitive that we open sourced: p751sidh. The Quantum Threat Most of today's cryptography is designed to be secure against an adversary with enormous amounts of computational power. This means estimating how much work certain computations (such as factoring a number, or finding a
At Cloudflare our focus is making the internet faster and more secure. Today we are announcing a new enhancement to our HTTPS service: High-Reliability OCSP stapling. This feature is a step towards enabling an important security feature on the web: certificate revocation checking. Reliable OCSP stapling also improves connection times
The Internet is getting more secure every day as people enable HTTPS, the secure version of HTTP, on their sites and services. Last year, Mozilla reported that the percentage of requests made by Firefox using encrypted HTTPS passed 50% for the first time. HTTPS has numerous benefits that are not
