Managing secrets across multiple hosts in a Nix environment requires encrypting values into host-specific YAML files and referencing them via sops-nix modules. This approach uses age encryption and a configured .sops.yaml file to define key groups and scope access.

Rotating encryption keys for sops-nix involves updating the key groups defined in your .sops.yaml file and re-encrypting the affected secret files. This ensures that retired keys can no longer decrypt the updated secrets across your hosts and users.

Yes, you need age and a configured .sops.yaml file to use sops-nix for secret management. The .sops.yaml file defines key groups and host or user scopes, while age provides the underlying encryption mechanism for securing your secret values.

Yes, you can securely access encrypted secrets during system boot with sops-nix. By wiring sops.secrets references into your Nix modules, the system automatically decrypts and mounts secrets at boot time or during user sessions based on your configuration.

Debugging secret access issues in a multi-user Nix setup involves checking the host and user scopes defined in your .sops.yaml file. You should validate that the correct age keys are present and verify runtime decryption access controls through provided testing steps.

Decrypted secrets may not be accessible in your Nix module if the sops.secrets references are not correctly wired or the host lacks the proper age key. Check your .sops.yaml configuration to ensure the host and user scopes match the intended access controls.
