Utilize HMAC access ID/secret keys instead of JSON authentication file

[ghost]

Hello,

Is there any way we can utilize HMAC access id and secret key rather than passing the authentication JSON? I tried to find documentation on this but wasn't able to find anything. I saw a mention of setting environmental variables for this but couldn't find much. Overall, it would be preferable to pass these as regular variables instead.

Thanks,
Santosh

I haven't heard of HMAC before, I found this. https://cloud.google.com/storage/docs/authentication/hmackeys

There are signed URLs for authenticated access, does that suit your use case?

There are some examples here on how to create the HTTP headers

You could perhaps look at generating those using curl or otherwise, if I have some working examples I can look at then they can be built using googleAuthR etc.
