S3 Storage Encryption

[BEBU88]

Is your feature request related to a problem? Please describe.

I would like to move my files to S3 storage.

Describe the solution you'd like

Actually I'm using LUKS encrypted block storage to store my files. It would be much cheaper just to store metadata on block storage. Therefore I would like to have the option to encrypt my files at client side with a password for all blobs before they're uploaded to a bucket. At least there should be the option to use S3 SSE-C.

Describe alternatives you've considered

Using s3fs-fuse could be an option, but I actually would prefer a native solution.
