Is anyone aware of an alternative to crt.sh ? I really like the website, and it's simple visualization. No bloat around it, just the pure purpose of providing insights from CT logs.

However, the website quite often returns server errors, and others. More often than it did in the past, a few years ago. My hope is, to find a similarly informative tool that is however a bit more reliable.

I dislike it if I have to put down a note to re-check a domain's certificate history and to remember just because the service was down by the time I was interested in the information.

AI Infrastructure Exposes Widespread Security Gaps

A staggering 2 million hosts and 1 million exposed services were uncovered through a simple scan of certificate transparency logs, revealing alarming security gaps in AI infrastructure. The findings painted a concerning picture: most AI projects lack even basic authentication, leaving them vulnerable to…

Merkle Tree Certificate support is already in Chrome. Soon, it will be everywhere.

Ars Technica

Today I published an update on the #Canonical supported #upki project, which brings browser-grade Public Key Infrastructure to Linux through the efficient #CRLite data format, with the core revocation engine now functional and available to test!

Beyond current progress, this post explores broader integration, performance, and future capabilities like Certificate Transparency enforcement and Merkle Tree.

This is all part of the effort to increase the resilience of #Ubuntu machines by default, but I hope it has a wider benefit on the Linux ecosystem going forward!

An update on upki

Last year, I announced that Canonical had begun supporting the development of upki, a project that will bring browser-grade Public Key Infrastructure (PKI) to Linux. Since then, development has been moving at pace thanks to the tireless work of Dirkjan and Joe. In this post, I’ll explore the progress we’ve made, how you can try an early version, and where we’re going next. Architecture & Progress As a reminder, upki’s primary goal is to provide a reliable, privacy-preserving, and efficient cer...

lol. I minted a new TLS cert and it seems that OpenAI is scraping CT logs for what I assume are things to scrape from, based on the near instant response from ...

Eric Brandes dropped Part 2 of our CT logs series. The performance gap is staggering.

Tiled logs: 100M+ records/day
RFC 6962: Low millions (with throttling)

Google throttles hard. Cloudflare's Nimbus is decent. Let's Encrypt's tiled logs absolutely fly.

Searching Certificate Transparency Logs (Part 2)

In this post we'll write Golang code to pull Certificate Transparency Log entries and process them at scale.

CertKit SSL Certificate Management

Certificate Transparency logs hold billions of certificates but searching them is brutal. crt.sh is slow, truncates results, and crashes constantly.

We built a better CT search tool at CertKit (free to use). Part 1 of my series explains why CT exists (DigiNotar hack), how it works, and the insane scale (96M certs/week).

Searching Certificate Transparency Logs (Part 1)

Searching Certificate Transparency logs lets you uncover every SSL/TLS certificate ever issued for your domain. You can detect mis-issuance, unauthorized changes, or shadow infrastructure before it becomes a problem. It’s a good way to monitor your digital identity and maintain trust in your organization’s security posture.
