16 The auth.json file stores encrypted authentication information for the
17 user to container image registries. The file can have zero to many
18 entries and is created by a login command from a container tool such as
19 podman login or buildah login. Each entry includes the name of the
20 registry and then an auth token in the form of a base64 encoded string
21 from the concatenation of the username, a colon, and the password.
