A method of securing data on an electronic device comprises allowing a user of the device to select one of an encryption and decryption operating mode and an encryption only operating mode. The encryption and decryption operating mode requires that the device have access to a user passphrase, and the encryption only operating mode does not require that the device have access to the passphrase.
