# 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
|
||
#
|
||
# 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
|
||
# you may need to re-encode all the secrets (even physically deleting and recreating them).
|
||
#
|
||
# 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;
