The des driver provides a high level interface to the AmZ8068 Data Ciphering Processor, a hardware implementation of the NBS Data Encryption Standard.
The high level interface provided by this driver is hardware independent and could be shared by future drivers in other systems.
The interface allows access to two modes of the DES algorithm: Electronic Code Book (ECB) and Cipher Block Chaining (CBC). All access to the DES driver is through ioctl.2 calls rather than through reads and writes; all encryption is done in-place in the user's buffers.
