Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Everything below the separator bar is a mirror of the "Find Alternatives for Ourselves Megathread: Third Strike" post by bettervanilla on the r/RedditAlternatives subreddit, found here.

It was last updated on 2023, Aug 6 at or around 1325 EDT. It may or may not get updates going forward, depending on how much free time I have (e.g. don't expect me to update it but I might if I have time). Also, if bettervanilla decides to move his post off of reddit, I plan to update this page to redirect to the new location.

Also found one more really nice list mentioned on the r/linuxmasterrace sub while trying to find where they are migrating to. Thanks to /u/ball_soup for sharing!

Let's Destroy C

I have a pet project I work on, every now and then. CNoEvil.

The concept is simple enough.

What if, for a moment, we forgot all the rules we know. That we ignore every good idea, and accept all the terrible ones. That nothing is off limits. Can we turn C into a new language? Can we do what Lisp and Forth let the over-eager programmer do, but in C?
