NAME    [Toc]    [Back]

     safe - SafeNet crypto accelerator

SYNOPSIS    [Toc]    [Back]

     safe* at pci? dev ? function ?

DESCRIPTION    [Toc]    [Back]

     The safe driver supports cards containing any of the following chips:

           SafeNet  1141   The  original  chipset.  Supports DES,
Triple-DES, AES,
                         MD5, and SHA-1 symmetric  crypto  operations, RNG, public
 key operations, and full IPsec packet processing.

           SafeNet 1741  A faster version of the 1141.

     The safe driver registers itself to accelerate DES,  TripleDES, AES,
     MD5-HMAC,  and  SHA1-HMAC  operations for ipsec(4) and crypto(4).

     Additionally, the driver registers with crypto(4) to  accelerate modular
     exponentiation of up to 2048-bit operands and provides input
to the
     random(4) subsystem.

DIAGNOSTICS    [Toc]    [Back]

     safe%d: Reduce max DMA size to %u words for rev  %u.%u   The
1.0 silicon
     has  major  pci(4)  bugs  and  may  lock the bus completely.
There is no easy
     workaround.

BUGS    [Toc]    [Back]

     Early silicon revisions can wedge the PCI bus.
