I rewrote my 2012 self-signed cert generator in Go – cert-depot.com▲9
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.

Hi everyone! So a couple of weeks ago I was building a chrome extension for crawling data and uploading it somewhere online for further exploration. I found myself struggling a lot with this as I found every solution I tried hard to implement (Firebase, Mongo Atlas, EC2). I mean I only needed a simple endpoint in which I was able to set and get JSON data with some key. In the end I made a small CRUD using Mongo, Sinatra, Puma, and Nginx. Then Chrome complained that my endpoint (raw IP) was not HTTPS so I bought a cheap domain and configured an SSL certificate into my server. I found this to…

Website for creating self-signed certificates▲6
If you're developing locally and need to use HTTPS for whatever, then this tool is hopefully useful to you. I made it because there's a lot of bad info online about generating self-signed certificates. For instance, a lot of guides don't use the SAN list extension or show you how to create a proper certificate chain. Firefox doesn't allow a CA certificate to be used as an end certificate. Getting a working certificate can get pretty confusing, especially for newcomers to certificates or webdev. Having a website for this also means the process of getting a certificate is the same, no matter…
