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
- safe0: Reduce max DMA size to N words for rev X.Y
- 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.
