What exactly to put on key: 'KEY_CONTENTS' ?

[msantosfelipe]

In my case I cant use the keyFile, so what to put on this
// the cryptographic key as a string, can be the contents of the PEM file
// the key will be used to sign the JWT and validated by Google OAuth
key: 'KEY_CONTENTS',

Can u give an example of that? On the PEM file I have PRIVATE KEY and CERTIFICATE

@extrabacon was this ever resolved? I'm trying to pass in the "KEY_CONTENTS" as an environment variable so I can use the authentication with different projects.
