implement it for nCipher hardware. The interface in itself should be clear enough, but the nCipher implementation is currently not the best when it comes to getting a passphrase from the user. However, getting it better is a little hard until a better user interaction method is create. Also, use the possibility in req, so we can start to create CSR's with keys from the nForce box. WARNING: I've made *no* tests yet, mostly because I didn't implement this on the machine where I have an nForce box to play with. All I know is that it compiles cleanly on Linux...
The stuff in here is based on patches supplied to me by Steven Schoch <schoch@sheba.arc.nasa.gov> to do DSS. I have since modified a them a little but a debt of gratitude is due for doing the initial work.
