Sops

Provide every user's SHA512 hashed password to your host's secrets.yaml:

Replace abc123 with your actual secrets

radicale:
    user1: abc123
    user2: abc123
    # ...

Generate hashed passwords with:

nix-shell -p openssl --run 'openssl passwd -6 <password>'

Setup

Set a CNAME record for your Radicale subdomain (dav by default) pointing to your domain.

Add two SRV records:

Calendar:

• type: SRV
• name: _caldavs._tcp
• priority: 0
• weight: 1
• port: 443
• target: dav.domain.tld.

Contacts:

• name: _carddavs._tcp

rest as above
