PHP version (eg, 5.6): 5.6.30
Yesterday I reinstalled Nextcloud, after screwing up an upgrade from 10 to 11. (did it together with a server migration and accidentally ran some commands on the old server which still had v10 installed) When everything was working nicely, I decided to enable encryption.
Reading the admin manual, I just copy/pasted commands into my SSH session without reading the whole page first, so I just read the part about recovery keys afterward. I did however see the warning about an approximate increase in size of about 35%, so I added 50% of extra space to my data volume. Then I started occ encryption:encrypt-all and went to sleep. This morning, I discovered that my entire volume had been filled, so I extended it again, but when I logged in I got the Invalid private key for encryption app. Please update your private key password in your personal settings to recover access to your encrypted files. warning in my screen.
Problem is, I’ve never set any password or recovery key, nor did I change the password of my account recently. Disabling encryption does not get me my files back, occ encryption:decrypt-all wants my recovery key password, which I’ve never set, occ encryption:decrypt-all username with the user’s login password throws an [OC\HintException] Bad Signature
Is there anything I could try, or is starting from scratch again and re-adding my data the only option?
