# SOPS configuration:
# docs: https://github.com/Mic92/sops-nix
#
# for each new user you want to edit sops files:
# create a private age key from ssh key:
# $ mkdir -p ~/.config/sops/age; ssh-to-age -private-key -i ~/.ssh/id_ed25519 > ~/.config/sops/age/keys.txt; chmod 600 ~/.config/sops/age/keys.txt
# if the private key was password protected, then first decrypt it:
# $ cp ~/.ssh/id_ed25519 /tmp/id_ed25519
# $ ssh-keygen -p -N "" -f /tmp/id_ed25519
#
# for each user you want to decrypt secrets:
# $ cat ~/.ssh/id_ed25519.pub | ssh-to-age
# add the result to .sops.yaml
# since we specify ssh pubkeys in the nix config, you can just grep for `ssh-ed25519` here and use those instead
#
# for each machine you want to decrypt secrets:
# $ cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age
# add the result to .sops.yaml
# $ sops updatekeys secrets/example.yaml
#
# to create a new secret:
# $ sops secrets/example.yaml
# control access below (sops.secret.<x>.owner = ...)
#
# to read a secret:
# $ cat /run/secrets/example_key
# sops.age.sshKeyPaths = [ "/home/colin/.ssh/id_ed25519_dec" ];
# This will add secrets.yml to the nix store
# You can avoid this by adding a string to the full path instead, i.e.
# sops.defaultSopsFile = "/root/.sops/secrets/example.yaml";
sops.defaultSopsFile = ./../../secrets/example.yaml;
# This will automatically import SSH keys as age keys
sops.age.sshKeyPaths = [
"/etc/ssh/ssh_host_ed25519_key"
# "/home/colin/.ssh/id_ed25519_dec"
];
# This is using an age key that is expected to already be in the filesystem
# sops.age.keyFile = "/home/colin/.ssh/age.pub";
# sops.age.keyFile = "/var/lib/sops-nix/key.txt";
# This will generate a new key if the key specified above does not exist
# sops.age.generateKey = true;
# This is the actual specification of the secrets.
