Encryption
Mobile Encryption uses a symmetric-key algorithm for
encryption and descryption. This means that only one key
is used for both processes. The key is created when the
device is hard reset, and is accessible by Priviledged
application only. If the key is ever corrupted or lost(the
device is hard reset), then you will not be able to decrypt
any of the encrypted files, and you will have lost your
sensitive information.
