File Encryption disabled but files are still encrypted

Hi,

i noticed that for at least one user on my nextcloud installation some files are not readable anymore. not all, only some of them. While debugging i noticed that the files have an encryption header and the files seem to be encrypted.

File starts with:

HBEGIN:oc_encryption_module:OC_DEFAULT_MODULE:cipher:AES-256-CTR:signed:true:HEND-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

When I run the occ encryption:decrypt-all, i get the following output.

root@debian-4gb-nbg1-dc3-1 /var/www/cloud/pages # sudo -u www-data php occ encryption:decrypt-all
Server side encryption not enabled. Nothing to do.
root@debian-4gb-nbg1-dc3-1 /var/www/cloud/pages #

Is there a way to troubleshoot this? I also noticed that for the corresponding files there is an existing keypair in the data folder structure data/user/files_encryption/keys/ …

Is there a way to encrypt the files by hand?
Is there a way to check if the keys in the data folder are valid for decryption of the real files?

Please help!

Best regards
Philipp

Meanwhile i tried to enable encryption which gave me the following:

root@debian-4gb-nbg1-dc3-1 /var/www/cloud/pages # sudo -u www-data php occ encryption:enable
Encryption is already enabled

No encryption module is loaded
root@debian-4gb-nbg1-dc3-1 /var/www/cloud/pages #

Ignoring this, I tried to run a occ encryption:decrypt-all again. This time it said it successfully decrypted the files but i can see that the files are untouched…

Sorry to bump a dead thread, I was wondering if you’ve had any luck with this. It seems my server encryption randomly got enabled and this is the issue I’m facing as well.
