Login to ownCloud as the admin user. You might be asked for an upgrade, if the E2EE app was installed before.

Administration Setup

Open the Admin Settings and visit thesection. Enter your license key in the provided text area:
Select, which key storages will be available for your users. You may provide different settings for ownCloud and guest users.

If you provide more than one key storage options, users have to set up their key storage in their personal settings prior to being able to read and save encrypted files. This must be communicated in advance to avoid any confusion.
By default all users are enabled to use the E2ee app. If you want to restrict usage to specific groups only, you may set them in the Authorized Groups section. If you provide one or more groups here, only members of those groups may set a folder as E2ee encrypted. Click the apply button, when you are done.
If you have the Guests app installed, make sure e2eeshare is added to the app whitelist. The Guests app is found in thesection.

FAQ

I got a valid license, but when installing it, I still get a message that the system is unlicensed.

This usually happens, when you did not specify correct URL(s) for your license keys. Make sure to send us the exact URL(s) the system will be visible from (i.e. https://example.com/owncloud) -> basically everything before index.php. If you plan to use different URLs for the same installation make sure to send us all of them.

The installation did not create the correct tables.

The E2EE app uses 4 tables. On some system configurations the update seemed to fail. Please notify us of your configuration so we can fix the issue.

If you want to manually add the tables here is the current schema:
