Is there a way to prevent data tampering when using rclone?

Last couple of questions

So you run this on the local backup before pushing to the cloud and since you saved this list to the root of the backup rclone just automatically picks this file up and sends it to the cloud?

So basically if I think my encryption password AND the cloud account password was compromised. I'm screwed for data integrity? At this point I can no longer be certain my files were not compromised?

EDIT: I guess I can check history since a lot of online providers will tell me if something was edited.
