Files Encryption
|
|
================
|
|
|
|
ownCloud ships a encryption app, which allows to encrypt all files stored in
|
|
your ownCloud. Once the encryption app was enabled by the admin all your files
|
|
will be encrypted automatically. Encryption and decryption always happens
|
|
server-side. This enables the user to continue to use all the other apps to
|
|
view and edit his data. But this also means that the server administrator could
|
|
intercept your data. Server-Side encryption is especially interesting if you
|
|
use external storages. This way you can make sure that the storage provider is
|
|
not able to read your data.
|
|
|
|
Please remember. Once the encryption app is enabled you need your log-in
|
|
password to decrypt and access your data. By default your data will be lost if
|
|
you loss your log-in password. If you want to protect yourself against password
|
|
loss store your log-in password on a secure place or enable the recovery key
|
|
as described below.
|
|
|
|
What gets encrypted
|
|
-------------------
|
|
|
|
The current version encrypts all your files stored in ownCloud.
|
|
|
|
At the moment we don't encrypt:
|
|
|
|
- old files in the trash bin (files which were deleted before the encryption app was enabled)
|
|
- image thumbnails from the gallery app and previews from the files app
|
|
- search index from the full text search app
|
|
|
|
All this data is stored directly on your ownCloud server, so you don't have to worry to expose
|
|
your data to a third party storage provider.
|
|
|
|
Decrypt your data again
|
|
-----------------------
|
|
|
|
If the encryption app was disabled users can decrypt their files again in their
|
|
personal settings. After this was done they can continue to use their ownCloud
|
|
without encryption.
|
|
|
|
|
|
Settings
|
|
--------
|
|
|
|
Once the encryption app is enabled you will find some additional settings on
|
|
your personal settings page.
|
|
|
|
Recovery Key
|
|
~~~~~~~~~~~~
|
|
|
|
If the admin enabled the recovery-key you can decide by your own if you
|
|
want to use this feature for your account. If you enable "Password recovery"
|
|
the admin will be able to read your data with a special password. This allows
|
|
him to recover your files in case of password loss. If the recovery-key is not
|
|
enabled than there is no way to restore your files if you loss your log-in
|
|
password.
|
|
|
|
Change Private Key Password
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This option will be only available if your log-in password but not your
|
|
encryption password was changed by your admin. This can happen if your ownCloud
|
|
provider uses a external user back-end, e.g. LDAP, and changed your log-in
|
|
password there. In this case you can set your encryption password to your new
|
|
log-in password by providing your old and new log-in password. The encryption
|
|
app only works if log-in password and encryption password is identical.
