TLS

Cloudflare has published a blog post detailing its work building a certificate authority intended to operate at the scale of the entire Internet. The piece explains the engineering and trust requirements behind issuing TLS certificates that browsers rely on. It is drawing attention among developers and security engineers discussing how web encryption infrastructure is run at scale.

Cloudflare has announced work on a certificate authority designed to serve the entire Internet, detailing the technical and operational challenges of issuing TLS certificates at global scale. The post, also drawing attention on Hacker News, walks through how a CA must balance security, automation and trust to keep encryption working across the web.

Cloudflare announced on Tuesday that it plans to issue quantum-proof TLS certificates, positioning itself among the first certificate authorities to use cryptography widely believed to withstand attacks from quantum computers. The move anticipates a future in which quantum machines could break today's encryption, and it puts the web infrastructure company ahead of much of the industry in securing internet traffic against that threat.

A new entry has been added to cybersecurity conference listings: ATLSECCON, taking place April 8-9, 2027 in Halifax, Nova Scotia, Canada. The Atlantic Canada security gathering is now on the calendar for infosec professionals planning next year's event schedule, with details available on its official website.

A maximum-severity security flaw, tracked as EUVD-2026-81591, has been disclosed in vm2, the Node.js sandbox library maintained by Patrik Simek. The vulnerability, rated 10.0 out of 10 under CVSS v3.1, allows the NodeVM component to replace the host process TLS trust store, potentially undermining certificate validation. The advisory was updated on 1 October 2026 and appears in the EU vulnerability database.

wolfSSL announced that its TLS library now supports the ACE cryptographic accelerator on NXP's S32K3 microcontrollers. The integration enables hardware-accelerated encryption on the automotive-grade S32K3 family, improving performance and efficiency for embedded security applications. The announcement is circulating among embedded and cryptography communities interested in secure automotive and industrial systems.

Cloudflare has announced it is now operating as a certificate authority, issuing TLS certificates at global scale. The company says the move is aimed at making secure HTTPS connections more accessible to everyone, building on its existing infrastructure business. The announcement is drawing attention from developers and security professionals discussing what a new large-scale CA means for the web's certificate ecosystem.

Cloudflare has announced plans to issue quantum-safe TLS certificates as part of a major overhaul of the website authentication ecosystem. The move is aimed at protecting encrypted web traffic against future attacks by quantum computers, which could eventually break today's widely used cryptographic algorithms. Security watchers are highlighting it as a significant step toward post-quantum encryption across the web.

NASA's Astronomy Picture of the Day website is currently inaccessible to visitors because its TLS certificate is issued for go-vip.co rather than nasa.gov or apod.nasa.gov, triggering browser security warnings. go-vip.co redirects to WordPress VIP, suggesting the agency's hosting provider generated the site certificate incorrectly. Users are sharing the error online as they try to view the popular daily image page.

A system administrator ran a TLS check against apod.nasa.gov and found the site's certificate chain shows a validity window starting in late 2026, issued via Let's Encrypt. The odd future-dated dates have drawn amused attention from tech observers, who note that such entries usually point to certificate misconfiguration or overlapping issuer logs rather than anything nefarious. NASA has not commented on the quirk.
