Wow ... wait a sec.
You mean that there is NO RSA support in the /dev/crypto?
If I get it right this means that there is virtually NO card
(even with the fastest RSA) that I could use? Or at least
not to accelerate the RSA computations because the kernel
does not support the interface to the card for RSA?

I am primarily interested in accelerating the SSL handshake
and since I am using RSA key exchange (with 2048 bit keys)
this means that I better forget about those cards at all?

It is interesting that on the's site they say:

Rainbow Technologies' Cryptoswift SSL Acceleration product line is
in its support of major operating systems and web servers such as:


-Microsoft IIS
-C2Net Stronghold

What kind of support do they mean? Just symmetric chipers or what?

Thank you for your reply
