Re: [TCLUG:14564] Hardware accelerator under linux?

[Peter Lukas <peter@math.umn.edu>]

I've only seen them available for commercial products, like the
Chrysalis-ITS.  It's PCI, and will eventually make its way into the Nokia
firewall (ala OpenBSD), so there's a potential for it to eventually make
its way into the Linux kernel.

Redcreek makes a IPSec adapter for NT, and it's boasted to be supported
under Linux 2.2.  It'll handle DES and 3DES at an advertised 45Mbps.
They don't offer any prices on their website, so you'll probably have to
speak with a rep:
http://www.midwestlinux.com/products/redcreek/ipsecpci.html
or at 
http://www.redcreek.com/products/ipsec.html
The press release is here:
http://www.redhat.com/partners/press_partner_redcreek.html

For the time being, I'd hit up a faster encryption cipher like blowfish
(if you haven't already).  You may also want to disable compression and
other extraneous cpu-intensive functions (besides, the blowfish
compression algorithm has some exploitable features).
