AreMyKeysSafe

What it does

If you have been in the Web space for a number of years, there's a good chance that you are still using some SSH keys you generated 13 years ago. 👵 They might be considered unsafe by today's standards. This app helps you check for that. 🏰

Is it still safe?

First, you must know that GitHub and GitLab publish your public SSH keys, which means all SSH keys you registered with them. This in itself is not an issue, and it’s useful if you want to send someone an encrypted message or add SSH keys to the authorized list on some device. This website fetches those public keys and analyzes them. On GitHub that could be https://github.com/dz0ny.keys and on GitLab https://gitlab.com/dz0ny.keys . Then a small Golang application is run as WebAssembly in your browser. This way, even if you have an outdated key (we will talk about this below), I won’t know. Bash alternative for this kind of check would be ssh-keygen -l -f ~/.ssh/<public_key>.pub . How can SSH…from aremykeyssafe.com

  Keypub.sh – OAuth for the terminal using SSH keys2024 · keypub.sh · ▲222

  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:&#x2F;&#x2F;github.com&#x2F;skariel&#x2F;keypub

  Talanoa▲346

  Hi 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…

  Warp, a Rust-based terminal▲946

  Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…
