---------------------------------------------------------------------
your flow credentials file is encrypted using a system-generated key.
if the system-generated key is lost for any reason, your credentials file will not be recoverable, you will have to delete it and re-enter your credentials.
you should set your own key using the 'credentialsecret' option in your settings file. node-red will then re-encrypt your credentials file using your chosen key the next time you deploy a change.
