    From the cryptic terminal commands to the innumerable ways to shoot yourself in the foot, I always struggled to use TLS certificates. I love how much easier (and cheaper) Let's Encrypt made it to get certificates, but there are still plenty of things to struggle with. That's why we built Relay: a free, browser-based tool that streamlines the ACME workflow, especially for tricky setups like homelabs. Relay acts as a secure intermediary between your ACME client and public certificate authorities like Let's Encrypt. Some ways Relay provides a better experience: - really fast, streamlined…

    TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i…

    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.
