As answered by people managing SpeedFan 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.

I use an app to check system temps: OpenHardwareMonitor. Some people like SpeedFan, does most of the same stuff. Source: almost 4 years ago
That's not super common (but it does happen ofc). It might be worth running a tool to scan the drive and take a peek at the SMART data. I typically use Speedfan https://almico.com/speedfan.php. Source: almost 4 years ago
You'll get better gpu support from Afterburner, but if you have a weird chipset or an incompatible fan controller, good old SpeedFan still has a few tricks. 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
