A signature value is provided which is stored in a signature device. The signature device is capable of being inserted into and removed from a computer system. A textual description of the data is created. The data is encrypted utilizing both the signature value stored on the device and the textual description. The encrypted data is then stored on the hard disk drive. The data processing system does not permanently store encryption keys.
