NAME
     dca - Crypto Accelerator device driver

DESCRIPTION
     The dca device driver is a multi-threaded, loadable hardware
     driver supporting Sun PCI-based (pci108e,5454) cryptographic
     accelerators, such as the Sun Crypto Accelerator 1000.


     The dca driver requires the  presence  of   Solaris  Crypto-
     graphic  Framework  for  applications  and kernel clients to
     access the provided services.

EXTENDED DESCRIPTION
     The dca driver maintains the following statistics:

     3desjobs        Total number of jobs submitted to the device
                     for 3DES encryption.


     3desbytes       Total number of bytes submitted to the  dev-
                     ice for 3DES encryption.


     rsapublic       Total number of jobs submitted to the device
                     for RSA public key operations.


     rsaprivate      Total number of jobs submitted to the device
                     for RSA private key operations.

Devices                                                   dca(7D)



     dsasign         Total number of jobs submitted to the device
                     for DSA signing.


     dsaverify       Total number of jobs submitted to the device
                     for DSA verification.


     rngjobs         Total number  of  jobs  submitted  for  pure
                     entropy generation.


     rngbytes        Total  number  of  bytes  of  pure   entropy
                     requested from the device.


     rngsha1jobs     Total number of jobs submitted  for  entropy
                     generation, with SHA-1 post-processing.


     rngsha1bytes    Total number of bytes of  entropy  requested
                     from the device, with SHA-1 post-processing.



     Additional statistics may be supplied for Sun  support  per-
     sonnel,   but  are not useful to end users and are not docu-
     mented here.


     The dca driver can be configured by defining  properties  in
     /kernel/drv/dca.conf  which  override  the default settings.
     The following properties are supported:

     nostats      Disables the  generation  of  statistics.  This
                  property  may  be  used to help prevent traffic
                  analysis, but this may inhibit support  person-
                  nel.


     rngdirect    Disables the SHA-1 post-processing of generated
                  entropy.  This may give "truer" random numbers,
                  but it may also introduce the risk of  external
                  biases  influencing  the  distribution  of gen-
                  erated random numbers.
