Can you explain why we would ever want a userspace interface to it? doing crypto in kernel for userspace consumers sis simply insane. It's computational intensive code which has no business in kernel space unless absolutely required (e.g. for kernel consumers). In addition to that adding the context switch overhead and address space transitions is god awfull too. This all very much sounds like someone had far too much crack.
