A token is guaranteed to be a valid ASCII string (being composed of base64 encoded parts). The `encodedAuthParamString` are common to all the auth providers and are a way to pass implementation specific configs. In case of token auth, we're taking the "token" string itself. I didn't want to use `data:` here to simplify the user input. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
