Actually with crypt we dont get hashing but coping rencrypted files directly ( eg acd:/crypt gdrive:/crypt hashing is working. ( @ncw correct me if iam wrong)
I wonder if we may be we could make a ffmpeg script that checks all file as ffmpeg should report if video is corrupted. ( not 100% sure. )
@Stokkes could you run rclone check acd:/crypt gdrive:/crypt as this should show all corrupted files.
