Encrypting/Decrypting Data
If your HP iPAQ has been off for longer than the time you selected during setup, your data is encrypted.
When you turn the device on, you are prompted to authenticate using your PIN and/or password. After
successful authentication, your data is decrypted. This may take a few moments depending on the
amount of data you chose to have encrypted. However, encryption runs in the background, and you can
perform other tasks on your HP iPAQ during this time.
You can monitor the decryption process in two ways:
●
If you selected Display encryption status on the Encryption Settings screen during setup, the HP
ProtectTools window displays the decryption status.
●
If you choose not to display this status, the encryption/decryption process proceeds in the
background, allowing you to use your HP iPAQ for other purposes.
In either case, a Blue Lock icon appears in the Taskbar at the bottom of the Today screen during
decryption. When the icon disappears, decryption is complete. Typically the HP iPAQ responds more
slowly during the encryption/decryption process.
Authenticate and wait for the decryption process to complete before synchronizing using Microsoft
ActiveSync. If decryption is not complete before synchronization begins, ActiveSync may not be initiated.
To correct the problem, disconnect and reconnect the device after decryption is complete.
If you enable Server Synchronization on ActiveSync, it is recommended that you do not select a Mobile
Schedule to automatically initiate synchronization. Since authentication and decryption are necessary
when the HP iPAQ is turned on, automatic synchronization does not work properly when HP
ProtectTools is enabled. The same problem may also arise when using other server-based
synchronization products.
