Keypub.sh – OAuth for the terminal using SSH keys
Hi HN! I built KeyPub.sh to solve the problem of user verification for CLI applications. It's essentially OAuth for the terminal, but using SSH keys that developers and users already have. - No installation needed - works with existing SSH setup - Privacy-focused: users control what email info is shared - Simple email verification process - Free public service - Perfect for CLI app developers who don't want to build user verification Try it with: `$ ssh keypub.sh about` Source code: https://github.com/skariel/keypub
Keypub.sh – OAuth for the terminal using SSH keys launched on December 23, 2024 with 222 votes, #167 of 5,365 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Keypub.sh is an authentication service for command-line applications that uses SSH keys instead of passwords or traditional OAuth. Developers building CLI tools can integrate it to verify users without building their own authentication system. The service requires no installation, leverages SSH keys users already have, and gives users control over what email information is shared. It operates as a free public service and works by running a simple SSH command.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
