Encrypting your smartphone data
Your BlackBerry smartphone is designed to use encryption, with symmetric and asymmetric encryption algorithms and encryption keys, to protect your stored data.
When you turn on encryption in the security options, your smartphone encrypts data stored on your smartphone (for example, browser information, messages, tasks, and calendar entries), including data that your smartphone receives when it's locked. When you lock your smartphone with a password and your smartphone has secured your data, a closed lock indicator appears in the upper-left corner of the screen. If potentially malicious users attempt to access your data directly from the internal smartphone hardware, they can't decrypt and read the data without knowing your smartphone password.
You can set the encryption strength level to optimize either the encryption strength or the decryption time. More encryption strength means a longer decryption process. To maximize encryption strength, it is generally recommended that you increase the length of your smartphone password. If you set the encryption strength to "Stronger", use a minimum length of 12 characters for the smartphone password. If you set the encryption strength to "Strongest", use a minimum length of 21 characters for the smartphone password.
