Abstract
This disclosure relates to data storage device (DSD) hardware and, more specifically, to systems and methods for encrypting data stored on a DSD. A DSD comprises a non-volatile storage medium to store multiple file system data objects using block addressing. A device controller is integrated with the DSD and comprises hardware circuitry configured to encrypt data to be stored on the storage medium. The controller receives a request for an encrypted file system data object from a host computer system, identifies one of the ranges of blocks where the requested encrypted file system data object is stored on the storage medium, and sends the file system data object stored in the identified range of blocks to the host computer system in encrypted form as stored on the storage medium.
