As far as I am aware its not possible on any 08s or 12s, I think it may be available on some high end Coldfire devices.

Do you actually mean security rather than encryption? If so, see the flash blockguide for details. The security state of the microcontroller is governed by a byte stored in flash at address 0xFF0E.
