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...
patches that Geoff had in a patch file in his play directory.
NOTE for openssl-cvs: THIS IS A CVS BRANCH (BRANCH_engine). IT IS
NOT FOR THE FAINTHEARTED TO PLAY WITH. The code works as it is, but
it's not at all sure it ends up in the OpenSSL distributio in this
form, so do not get dependent on it!
Those rsyncing the repository are considered warned!
