As answered by people managing Cert Decoder and OncoDots.
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.
OncoDots's answer:
The will to help
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.
OncoDots's answer:
Oncology patients and their close ones
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.
OncoDots's answer:
A public library of easy-to-understand guides, over 90 recipes adapted to treatment side effects, a symptom journal that’s simple to show your doctor, medication and appointment reminders, short guided breathing exercises, caregiver guides — including caregiver rights under Law 24/2022 — and crisis resources, services, and rights for Romania, Italy, the United Kingdom, Germany, and the USA, also useful for the Romanian diaspora. OncoDots does not diagnose or recommend treatments: it always directs users to their medical team.

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
