  • Upcoming Changes to Let's Encrypt Certificates
    Haven’t tried it myself, but this one looks interesting: https://certifytheweb.com/. - Source: Hacker News / 9 months ago
  • We just hit $1M ARR in 4 years. With zero funding
    Always encouraging to see that ideas can work out. I'm not quite managing the "let's build a team" aspect just yet but otherwise similar journey and outcome over a (slightly) longer period. I just wanted to not deal with certificates, now I deal with certificates all day every day lol: https://certifytheweb.com. - Source: Hacker News / about 1 year ago
  • TLS Certificate Lifetimes Will Officially Reduce to 47 Days
    Pretty sure this only refers to publicly trusted certs. What percentage of public certs are still being manually managed? I've been in the cert automation industry for 8 years (https://certifytheweb.com) and I do still hear of manual work going on, but the majority of stuff can be automated. For stuff that genuinely cannot be automated (are you sure you're sure) these become monthly maintenance tasks,... - Source: Hacker News / over 1 year ago
  • SSL certificate lifetimes are going down. Dates proposed. 45 days by 2027
    This is largely a solved problem. On Windows https://certifytheweb.com has provided automated certificate management for the best part of a decade and we're now branching out into large scale cross-platform tools, for those interested. I was surprised by a customer yesterday who was looking to migrate thousands of manually renewed 1 year certs, I had no idea people were still using 1 yr certs to such a... - Source: Hacker News / almost 2 years ago
  • Running One-man SaaS for 9 Years
    Thanks :) - yes 90% of users are using the free version. It's a desktop app you install on servers. The API elements it does have are a combination of cloudflare workers, a windows server (for customer portal), linux for community discourse. Peak API use so far is 350M requests per month (was about $46 on cloudflare) but have managed to curtail that a bit. https://certifytheweb.com. - Source: Hacker News / about 2 years ago

  • Banana.dog back from the dead
    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
