I used Diffie-Hellman for that purpose years ago, and perhaps could
still dig up the code for it.  But I thought discrete logarithm had been
broken since then, or at least shown to be far less intractable than
people thought.  In any case, D-H is pretty slow --- are we prepared to
add seconds to the backend startup time in the name of security?
