SSL proxy client certificate rewrite to username/password

I want to use VoltDB's HTTP JSON interface 
   section 15.2.1

I also want to use certificate based authentication of the client. I am
thinking that I can use nginx as SSL frontend and have it rewrite the URL to
include  a randomly generated username and password as required by VoltDB.
But, I can't figure out how to write the rewrite rule in nginx's conf file.
I need to write multiple rules like this:
   if client certificate common name is X, add to URL the arguments,
user=PRF(x, u)&password=PRF(x, p) where PRF is a pseudo random function

Is this possible? How? I appreciate your help!
