If you're taking your tablet to work, your company's BYOD policy might require that you encrypt your tablet data. Encryption makes it far more challenging (if not impossible) for anyone to gain access to sensitive company data. But how do you achieve this? If you need an application for your end users, or if you're an end user who has been instructed to add encryption to your tablet, where do you turn? One free application that can handle this task is SSE - Universal Encryption App.
- Password manager
- Password generator
- Text encryption
- File encryption
- Master password app protection
- Secure wipe
- Strong encryption algorithm: AES(Rijndael) 256bit, RC6 256bit, Serpent 256bit, Blowfish 256bit/448bit, Twofish 256bit and GOST 256bit ciphers are available
- Algorithm benchmark
Let's walk through the installation and how to use a couple features of this handy, BYOD-friendly tool.
The installation of SSE is quite simple. Just follow these steps:
- Open the Google Play Store
- Search for "sse"
- Tap the entry for SSE - Universal Encryption App
- Tap Install
- Tap Accept & download
Once the installation is complete, the launcher will appear in the app drawer.
Using the Password VaultFrom the main screen (Figure A), you can access all of the various applications. Figure A
Here you see SSE running on a Verizon-branded Samsung Galaxy Tab.Tap on the Password Vault icon. At this point, you'll be prompted to set up a password for this feature. Make the password strong to prevent anyone from gaining access to the tool. Once you've set that password, you'll find yourself within the vault (Figure B). Figure B
You can use the default folders or create your own.
To create a new folder to house passwords, do the following:
- Tap the menu button (three horizontal lines)
- Tap New Folder
- Set the folders options (Figure C)
- Tap Save
- Tap the newly created folder
- Tap Add New Item
- Enter the details for the item (name, password, color, notes)
- Tap Save
You can order the folder alphabetically (A,B,C) or numerically (1,2,3).
When the item is created, the password will be hidden. If you tap on the entry, the password will be revealed. Because of this, make sure that you don't leave this feature open.
When setting a password, you'll also notice the inclusion of the random password generator. If you're in need of a password, this is a great way to create one that is stronger than what you'd typically create.
This is a really cool inclusion to the application. Say, for example, you want to hide a note from prying eyes but still want (somewhat) easy access to said note. To do this, you can write out the note in the SSE Text Encryption tool, encrypt the note, then copy the encrypted text to the system clipboard, and copy the text into a note. To regain access, all you have to do is copy the text back into the application and decrypt it. Here's how this is done.
- Open up SSE
- Tap on the Text Encryptor tool
- Enter a password for the encrypted text
- Confirm the password
- Type (or paste) the text to be encrypted into the upper pane (Figure D)
- Tap the Encrypt button
- Tap the bottom Copy button
- Paste the newly copied text into whatever application you need it in
A simple encoding test.
To decrypt the message, follow these steps:
- Go to the application you copied the text into
- Copy the encrypted text
- Open up SSE
- Tap on the Text Encryption tool
- Enter and confirm the password you used to encrypt the text
- Paste the encrypted text into the bottom pane
- Tap the Decrypt button
Your text should now be decrypted.
If you're looking for an easy way to protect passwords and text, this free Android app could be a handy addition to your BYOD environment. It's not as powerful as other tools, but its simplicity and cost make it fairly attractive. How do you encrypt data on your BYOD tablets? Share your experience in the discussion thread below.
