WOW. This is really, really, really good. I’ve been actually used with symmetrical ciphers in configs like bitlocker or truecrypt where there’s no extra checksum of any kind (never mind in any way vaguely crypto-secure) - understandably they want to have it one block = one block (any extra data has to be padded some place and it can create big trouble). But with this rclone becomes the tool of choice even to save local files, safe from (undetected) corruption and accessible from every platform. Sure, some files or folders might still go missing completely (making a note of the total size, another great feature of rclone Rclone is great - size command is unique AFAIK! Really! helps as well, not against malicious attacks replacing files with some of the same (total) size but in all “normal” situations).
