As answered by people managing ZEN 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

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Fair enough. I proceed as instructed, few days later someone from zen.com asks me to provide the transaction details and then I explain that there was no transaction. I provide evidence as needed. Source: about 4 years 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
