Sorry Greg but I'm not understanding what the issue is. Can you please explain a
bit more what you mean with the apis?

Our driver code is just a tube between proprietary code on the host machine and
proprietary code on the HSM. We are not trying to create our own linux crypto
apis because all the crypto stuff is happening in the existing proprietary code.
