As answered by people managing Kroki and Cert Decoder.
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.

The CLI sends the block to Kroki, gets back an image, and saves it locally. After committing the image to your assets repo, dev push replaces the code block with an image link pointing to GitHub — dev.to never sees the mermaid source.... - Source: dev.to / 6 months ago
In this blog post, we will implement a custom section helper that allows to invoke a Kroki.io server to generate images from almost every possible diagram as code language. - Source: dev.to / about 1 year 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
