My suggestion, if you were to take that route, would be to use the Engine 
interface rather than modifying the OpenSSL source. You could take the existing 
OpenSSL implementation of the functionality, move it into an engine (using one 
of the existing ones as a template), get that working, and then see about 
parallelizing it.

I created a modified version of the existing CAPI engine, and it wasn't 
particularly difficult. If memory serves, the OpenSSL wiki has some material on 
the subject too.

OpenSSL code does not do what you want.  You'll have to write it

Are you suggesting that I should modify openssl myself to expose that 
functionality or are suggesting that there is a way to do that given the 
already exposed functionality? If it is the latter could you point me in the 
right direction?

You'll have to write the code to do that parallelism yourself.
