For now it is always "1". The `private_key_id` and `private_key` is used for signing. The `ca_cert_path` is used for token server TLS certificate verification. After the JSON file is created, set `GOOGLE_APPLICATION_CREDENTIALS` environment variable to the JSON file path, then use the following code to create the credential:: import google.auth credential, _ = google.auth.default() credential = credential.with_gdch_audience("") We can also create the credential directly:: from google.oauth import gdch_credentials credential = gdch_credentials.ServiceAccountCredentials.from_service_account_file("") credential = credential.with_gdch_audience("") The token is obtained in the following way. This class first creates a self signed JWT. It uses the `name` value as the `iss` and `sub` claim, and the `token_uri` as the `aud` claim, and signs the JWT with the `private_key`. It then sends the JWT to the `token_uri` to exchange a final token for `audience`. cs6tt|||_||_||_||_||_||_dS)af Args: signer (google.auth.crypt.Signer): The signer used to sign JWTs. service_identity_name (str): The service identity name. It will be used as the `iss` and `sub` claim in the self signed JWT. project (str): The project. audience (str): The audience for the final token. token_uri (str): The token server uri. ca_cert_path (str): The CA cert path for token server side TLS certificate verification. If the token server uses well known CA, then this parameter can be `None`.
