It'd be great if there's no need to actually have a server to host the content. E.g., use a service like github.io to store a form of statically encrypted content that then gets a key from oauth to decrypt.
OAuth2 keys are more like session keys than decryption keys, that is, they are generated by Google during authentication, so it would not be possible to use them to decrypt previously encrypted static content. I would very much like to simplify the deployment, if you have any ideas or if I'm missing something, let me know!
