# secret handling with SOPS generate new age keys with `age-keygen -o ~/.config/sops/age/key-name.txt`. encrypt local secrets with `sops -e service-name/.env > service-name/.sops.env`. the action installs the pinned, checksum-verified SOPS build for the runner's OS/arch and decrypts every `*.sops.*` file except `.sops.yaml`, writing `service-name/.sops.env` back to `service-name/.env` via a temp file and atomic move.
