Abstract
One embodiment of the present invention provides a system that facilitates generating random data-encryption keys for data files. During operation, the system receives a command at a computer system to create a data file that may include encrypted data. This data file includes a wrapped data-encryption key to facilitate encrypting and decrypting data. In response to the command, the system generates a bit pattern to be used as the wrapped data-encryption key. Finally, the system creates the data file, which includes the bit pattern as the wrapped data-encryption key.
