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.

BUGS
Early silicon revisions can wedge the PCI bus.
