SOPS: Secrets OPerationS. Tool for managing secrets. More information: <https://github.com/mozilla/sops>.

• Encrypt a file:
  sops -e path/to/myfile.json > path/to/myfile.enc.json
• Decrypt a file to `stdout`:
  sops -d path/to/myfile.enc.json
• Rotate data keys for a sops file:
  sops -r path/to/myfile.enc.yaml
• Change the extension of the file once encrypted:
  sops -d --input-type json path/to/myfile.enc.json
• Extract keys by naming them, and array elements by numbering them:
  sops -d --extract '["an_array"][1]' path/to/myfile.enc.json
• Show the difference between two sops files:
  diff <(sops -d path/to/secret1.enc.yaml) <(sops -d path/to/secret2.enc.yaml)
