Cert Decoder
Cert Decoder is a free online tool that helps you decode X.509 SSL/TLS certificates in PEM format. It instantly shows important information like the issuer, expiry date, SAN entries, and fingerprint. All data is processed locally in your browser, so nothing is ever sent or stored elsewhere.

Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

When I developed Grotto, the runtime reference implementation for the Neander language (for more details read my related blog post series), I took the liberty, as a certified software architect, of first creating a full-blown arc42 architecture specification accompanied by a C4 model of Grotto. Since this was my own project, it was one of those rare opportunities where project management could not tell me that... - Source: dev.to / 3 days ago
The C4 model gives software teams a hierarchy for visualizing a system: context, containers, components, and code. It works like a map with zoom levels. At the widest view, we see the system, its users, and neighboring systems. Zooming in reveals applications, data stores, services, components, and relationships. - Source: dev.to / 24 days ago
C4[1]? Hadn’t heard of it until now. Thanks! Really curious what the major differences are that have you preferring it over other methods / winging it. [1]: https://c4model.com/. - Source: Hacker News / about 1 month ago
C4 model is a pragmatic approach to architecture modelling. There are many ways to introduce this into your architecture agent, for instance by using Structurizr syntax plus tooling as they also have official MCP servers. For now we're just going to rely on a simple skill from my GitHub repo and existing DrawIO MCP and skills. Configuration is super-simple, you just have to drop in the skill into... - Source: dev.to / 5 months ago
I've been working on this desktop tool (FSL license, free for commercial use) for the past month because I now spend more time in a terminal prompting Claude Code instead of using a code editor. It generally works quite well if I ask the right questions, but I still often find a lot of dead code, stubs, or poor architectural choices when I finish a session, and understanding the codebase itself can be jarring... - Source: Hacker News / 6 months ago
Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
