Show HN: I rewrote my 2012 self-signed cert generator in Go – cert-depot.com

dimastopel — Thu, 02 Apr 2026 12:36:10 +0000

Back in 2012 I built https://cert-depot.com as a weekend project. Node.js + Express + jQuery, shelling out to OpenSSL for certificate generation. It worked but I eventually let it rot. https://news.ycombinator.com/item?id=4766743

Rewrote it from scratch in Go. The entire thing is a single binary with no external dependencies:

1. Certificate generation uses Go's crypto/x509 (no OpenSSL)

2. Certificates are generated in memory and streamed directly — nothing is stored on the server

3. RSA 2048/4096 and ECDSA P-256/P-384

4. Subject Alternative Names (required by browsers since Chrome 58)

5. ZIP (PEM files) or PFX/PKCS#12 output

You comments / suggestions / bug reports are very welcome. Thanks.

Shameless plug: try Minimus! Minimalistic and always updated container images. We have the MinIO image and it is always up to date. https://www.minimus.io/

Show HN: My New Startup – Minimus

dimastopel — Sun, 04 May 2025 10:31:14 +0000

We create minimalistic and secure container base images. All images only contain the relevant package (e.g. python) and its dependencies. We even created our own Linux distro, called MinimOS, to be in control of all packages and build a new version as soon as it is available upstream. As opposed to Alpine Linux we mostly use glibc. Images are re-built daily and we continuously add more of them. By using our base images you can easily reduce the number of vulnerabilities by more than 90% (compared to Docker Hub). You can use our images for free (the 'latest' line) here: https://images.minimus.io. Have a wonderful day you all!

New comment by dimastopel in "Ask HN: Can you recommend a good nuclear power plant simulator?"

dimastopel — Tue, 11 Feb 2025 19:30:14 +0000

I know Rimworld and love it! I assume the mod is somehow similar to nuclear power management in Factorio?

Ask HN: Can you recommend a good nuclear power plant simulator?

dimastopel — Tue, 11 Feb 2025 18:37:02 +0000

Preferably a game that can run on Linux (not a must). Tried Nucleares but it doesn't run well on Linux using the latest Proton. Looking to learn, in detail, about how NPP works through operating it.

New comment by dimastopel in "Can Microsoft Flight Simulator help me learn to fly or make me a better pilot?"

dimastopel — Sun, 24 Dec 2023 13:54:36 +0000

I just got my PPL a year ago. My instructor did a survey among all students who got the license and among other things asked 1) how many flight hours did it take you to get the license 2) did you play with a simulator in your spare time. There was a clear inverse correlation between the two, meaning that those who did play with the simulator had to use less hours to get the license.

Imagine a search engine that gives you results without knowing your search query.
