Hi,
No on the SSH. Look at the specs, I think the 1401 cards will be
helpful only on older IPSec circuits.
I am not 100% sure here, I haven't looked at any of this in a few
years, this is just from recollection.

So the question is whether these cards, regardless of their affect on
throughput, increase usable CPU cycles? I have several Soekris 1401
cards and am wondering if there would be any point to putting them
into some machines that provide logins over ssh. These machines are
generally pretty good spec, 2.4GHz+, 1GB RAM, Intel MBs, mostly
on-board peripherals.
Given that spec of machine, I don't see that a hardware cipher would
offer much improvement -- and some of the available crypto
accelerators
don't perform Diffie-Helmann or AES, some do.
I myself have a ubsec(4) card, and even when I hacked OpenSSH to use
OpenSSL engine support by default (with someone else's patch), I
didn't
see that much improvement (even when I forced the use of MD5, RSA and
3DES).
I could be wrong though - the above is qualitative not quantitative.

BMS
