    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

    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…

    just wanted to share ward, a tool i hacked together to encrypt and manage sensitive files in a vault folder. it's written in bash and meant to be cloned and then stored using git or version control. you don't have to store it that way, it's just why i created it. what ward does: encrypts the files in ./vault/ into a single .gpg file, checks to see if your files have been tampered with, generates totp codes if you need them to recover critical accounts. how to use it: clone the repo, toss your files into the vault directory, and run yarn encrypt. now commit your new [private]…

    Hey HN! I made a service to share passwords easy and secure but never promoted it. It's called instapass.io I noticed that people besides my friends and clients actually started to use, so maybe it will be helpful for you too! You share one-time self-destruct message using one time links and I won't even be able to see what you wrote. How does it work? When you generate a message the client-side makes a random password and use that to encrypt the message. The password is appended as an anchor tag which all modern browsers never send to the server. This way, I don't even know what you shared.…
