This is a Drupal 8 module to manage storage of Google Secrets files, which are used by some applications that use the Google API.
The module defines a new plugin type, GoogleSecretsStore, and two initial implementations of the plugin, which store the secrets using a static file 'somewhere' on the filesystem, or a private drupal- managed file. The intent of the module is to enable site-designers to use other, potentially more secure or more flexible methods of storing this data.
You do not need this module unless a module using it depends on it.
