Hello All,
I am in the same dilemma as Andreas. I had all my files and my wifes
files (separate accounts) encrypted in owncloud. Things were working
well. The server was acting up so I decided to reinstall to a fresh
Ubunut 12.04LTS. I had my owncloud/data/ on a separate partition on a
RAID5 disk.
After resinstall, out of paranoia and to be safe, I copied the data
first to owncloud/data/ using regular cp command.
Our passwords are the same. My files are encrypted and I cannot
decrypted them any more. The encryption.key file is the the original
one. I wrote a php routine to decrypt the can decrypt the
encryption.key and I was able to retrieve its salt. For an expirement,
I encrypted a text file using owncloud and I still cannot decrypt the
text back. It decrypts in owncloud browser but not using a php
blowfish routines. I emailed Frank Karlitschek and he was nice enough
to respond. He said that the salt in the config.conf is used to
encrypt the password. I looked in the routines and found out that the
salt is generated in a random fassion. Then we are screwed. I cannot
believe we encrypt people's data against a random salt and without any
warning to tell people to copy the salt in a safe place just in
case????????????
Anyhelp will be greatly appreciated.

Quoting Andreas Heinlein <[email protected]>:
Hello,
I have recently set up a private ownCloud instance and enabled the
encryption app. This worked fine until I think the 4.0.3 update a few
weeks ago. From then, all encrypted files which are downloaded contain
merely random data; it looks like they're still encrypted. Unencrypted
files (Images etc.) can be downloaded and viewed just fine. Updating to
4.0.6 did not change anything. Password has not been changed since
initial setup.
A file 'encryption.key' exists in /var/www/owncloud/data/<user> and is
readable by the Apache user. Since I have come to the conclusion anyway
that I no longer need the enryption app: is there any way to manually
decrypt the files on the server?
Unfortunately, the encrypted files have also been sync'ed over the
unencrypted ones on my desktop, so I have no clear copy of those files
left. I have a backup of most of them, but not all.
Thanks for your help,
Andreas
