This article provides some answers to frequently asked questions about Sophos Secure Workspace available for Android and iOS.
Applies to the following Sophos product(s) and version(s) Sophos Mobile Encryption for AndroidSophos Mobile Encryption for iOS
Operating systems iOS 6, iOS 7, Android 4.x
On Android 4.3, the keys are saved within the key storage area secured by the operating system. On versions lower than 4.3, an app password has to be defined. The keys stored locally are secured by a key derived from this password.
Our application does not add any cryptographic information or functionality into the operating system. The keys are secured by the standard cryptographic functionality of iOS. Only applications using a specific Sophos certificate are able to access the keys imported by Sophos Secure Workspace.
No, this is not possible.
This depends on the way Sophos Secure Workspace was installed. If the application was deployed via Sophos Mobile Control then it would be a managed application. Managed applications are not part of iTunes backups and therefore the keys are not backed up. If the application was downloaded by yourself, you can create an encrypted backup using iTunes which contains all key information.
Click on the file attached to the email. For Android, the "Complete action using" view appears. For iOS the "Open with" view appears.
Within this, Sophos Secure Workspace is now listed with "Encrypt and store" (Android) or "Open in Workspace" (iOS). Once selected, you are able to specify a name, an encryption key and an upload location. Once everything is set, press the "Encrypt and store" button. If a cloud storage provider was chosen as the location, the app will upload the file directly if possible.
Yes, but a second application is required to do so. Open your cloud storage provider (such as Dropbox) and browse to the file location. Click on the file in question and press the "Share" button and then select "Open in,,,". Selecting "Open in Workspace" will open Sophos Secure Workspace and the upload dialog will appear. Select a key, the storage area and a folder in which you want to save the file.
Yes. Simply set the "Encrypt" option to "No".
No, you cannot reset the password.
Open the location of your cloud storage provider, e.g. Dropbox. Right click on the encrypted file and select "Import Key from file". Enter the pass phrase for the key in use. After entering the correct password, the key will be saved in your keyring and reported to the SafeGuard Management Center.
Yes, but only if you have the key in your SafeGuard Enterprise keyring. You will then have to re-encrypt the files with a key you know the password to.
All keys which have been imported to the device will be removed. Once the keyring is deactivated, you have to enter the password of the encryption key every time an encrypted file is opened.
The app protection password adds an additional layer of security. You can enable this feature in the settings of Sophos Secure Workspace.
For Android, the settings can be found by pressing the "settings" button within the app. On an iOS device the settings are available within the app at "Options | Settings".
You can create a new recovery password if you change your app protection password. Simply re-enabling the feature for the existing password is not possible.
If you still know the password for your encryption keys, you can simply uninstall the application and reinstall it as the app protection password will not be activated anymore.
