OpenSSL doesn't support it out of the box. What you're looking for
is something akin to
Ladar Levison has written an implementation which uses OpenSSL as a
backend. I tried finding it for you, but my connection (mobile, on
train) is so bad that I couldn't be bothered to keep trying.
If you google for it I'm sure you'll find it pretty easily. If you
can't find it -- it's not difficult to do it from scratch using that
wikipedia page and the OpenSSL reference manuals.
