A common way of distributing keys is by hosting them at a URL for download. This is not currently supported by the apt configure module, and would be a simple addition.

Example usage (note the suggested 'keyurl' key)

apt:
  sources:
      source1:
          keyurl: 'https://domain.io/keys/key1.gpg'
          source: 'deb [signed-by=$KEY_FILE] http://<url>/ jammy main'
