The goal of the Encryption app is to protect data on external storage. All files sent there will be encrypted by the Datto Drive server, and upon retrieval, decrypted before serving them to you (or those you shared them with). The key to decrypt the data resides on and never leaves the Datto Drive server.This makes the Datto Drive Encryption app a great tool to benefit from cloud storage offered by services like Dropbox or Google Drive while ensuring security and privacy of your data
To enable Encryption, follow these steps:
- Open the Admin page, as shown in Figure 1.

Sharing Encrypted Files
Only users who have private encryption keys have access to shared encrypted files and folders. Users who have not yet created their private encryption keys will not have access to encrypted shared files; they will see folders and filenames, but will not be able to open or download the files. They will see a yellow warning banner that says “Encryption App is enabled but your keys are not initialized, please log-out and log-in again.”
Share owners may need to re-share files after encryption is enabled; users trying to access the share will see a message advising them to ask the share owner to re-share the file with them. For individual shares, un-share and re-share the file. For group shares, share with any individuals who can’t access the share. This updates the encryption, and then the share owner can remove the individual shares.
Recovery Key Password
If your ownCloud administrator has enabled the recovery key feature, you can choose to use this feature for your account. If you enable “Password recovery” the administrator can read your data with a special password. This feature enables the administrator to recover your files in the event you lose your ownCloud password. If the recovery key is not enabled, then there is no way to restore your files if you lose your login password.

Files Not Encrypted
Only the data in your files is encrypted, not the filenames or folder structures. These files are never encrypted:
- Old files in the trash bin
- Image thumbnails from the Gallery app
- Previews from the Files app
- The search index from the full text search app
- Third-party app data
There may be other files that are not encrypted; only files that are exposed to third-party storage providers are guaranteed to be encrypted.
Change Private Key Password
This option is only available if your log-in password, but not your encryption password, was changed by your administrator. This can occur if your ownCloud provider uses a external user back-end (for example, LDAP) and changed your login password using that back-end configuration. In this case, you can set your encryption password to your new login password by providing your old and new login password. The Encryption app works only if your login password and your encryption password are identical.
