I can't access the contents of my encrypted files

[kulitnov852]

I encrypted a set of folders all containing files. I don't remember exactly if I checked all the encrypted files afterwards, but I deleted the non-encrypted files (the original files). Now I've noticed that the folders are there, the files are there, but when I open them they look empty.

The weirdest thing is that the size of the files seems a bit correct/accurate (because I've seen the names of my files (and again the type)). File sizes are not 0 bytes.

I've just noticed in the terminal after entering the command gocryptfs -fsck that a good number of my files are corrupt.

Ex :

...
doRead 807703: corrupt block re: stupidgen: message authentication failed
doRead 807703: corrupt block re: stupidgen: message authentication failed
fsck: error reading file "screenshot-2022-02-01 20.05.12.312.png" (inum 807703): read /tmp/gocryptfs.fsck.793716487/screenshot-2022-02-01_20.05 12.312.png: input/output error
fscheck summary: 72 corrupt, 0 files skipped

Is there any way of recovering them?

@kulitnov852 You could try to use the -forcedecode option with a gocryptfs version older than 2.2 when mounting the folder. This might still lead to corrupted data in the files but at least you should be able to access them by ignoring the integrity check failures.

You can use dd_rescue to recover the non-corrupt parts of the files. I would recommend this over using -forcedecode, but both are possible.

But something like this does not happen, usually. Where do you store the encrypted files? Some cloud filesystem / sync software?
