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!

FEATURE IMPLEMENTATION WORKFLOW

THIS IS A MANDATORY WORKFLOW - NO STEPS CAN BE SKIPPED

PHASE 1: RESEARCH & PLANNING (MANDATORY)

Step 1.1: Initial Research

YOU MUST USE ALL AVAILABLE RESOURCES:

Check existing usage rules via get_usage_rules MCP tool or CLAUDE.md links
Use package_docs_search for ALL potentially relevant packages

Trunk-based

Given a main branch used in a trunk-based development strategy, here is how semantic release can fit in:

%%{init: { 
    'logLevel': 'debug',
    'theme': 'default' , 
    'themeVariables': {
        'git0': '#777',

Thanks to the original blog post: https://equimper.com/blog/how-to-setup-tailwindcss-in-phoenix-1.4

1. Install `tailwindcss` and `postcss-loader` from npm:

cd assets
npm i --save-dev tailwindcss postcss-loader postcss-import

2. Initialize `tailwind` (still in assets directory)

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm
