### Summary

Calculate hash of the file during upload and compare it with the response provided from the cloud

### Motivation

Some cloud providers like pCloud return some metadata about the file object just created/modified after uploading without any further interaction. If it contains a hash, compare it with a hash created by the local file (can be calculated while streaming over the file during upload) to check if the file was uploaded correctly.

Implement this feature only for clouds that provide a hash directly after the upload was finished without further requests involved.
