Authenticating via Interoperable storage access keys

[mzjp2]

Hi,

I'm working on a project that implements connections to S3 via the super simple aws_access_key_id, aws_secret_access_key variables and I'd like to extend the functionality to include GCS access too.

GCS has similar functionality via their interoperability API but I can't seem to figure out how to use this to authenticate the connection to my bucket. Really, what I want to be able to do is pull the access key and secret from a file and use that to authenticate, without using the 'browser' token and caching. Is that possible from the current implementation?

Best, Zain

I wonder, can you use s3fs for this, since it's an s3-compatible protocol?
