SAFE(4)			  OpenBSD Programmer's Manual		       SAFE(4)

NAME
     safe - SafeNet crypto accelerator

SYNOPSIS
     safe* at pci?

DESCRIPTION
     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, Triple-DES, 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
     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.

SEE ALSO
     crypt(3), crypto(4), intro(4), ipsec(4), pci(4), random(4), crypto(9)

BUGS
     Early silicon revisions can wedge the PCI bus.
