Not that I know of, but it would be nice to have ;-)

Yes, OCF has provisions for cards that do public key type functions.
Checkout the safenet driver.

Get the source code from:
http://ocf-linux.sourceforge.net/
Look at the safenet driver, it's probably the cleanest and easiest to
follow. You can also look at the ixp4xx driver for a simple framework.
Both provide most the functionality available under OCF,
