As answered by people managing Semgrep 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.

Static Analysis & Semgrep: Do not rely on LLM alignment to write clean code. Enforce it. Write Semgrep rules to ban specific anti-patterns. If your standard dictates no default mutable values in Python methods, codify it. When the agent... - Source: dev.to / 19 days ago
I have noticed this in myself and in teams I have worked with: as output volume rises, review time does not rise with it. If anything, it compresses. The productivity gains are real. So is the risk they paper over. Tools like Semgrep and... - Source: dev.to / about 1 month 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
