I was confused from the brief documentation spec what is the difference between DH and Elliptic Curve code. I though these are two ways to do the same thing. It is only when I tried to get the x coordinate of the public key generated by generateKey() that I realized that this is not Elliptic Curve DH.

From @natalieesk and @rosatolen:

It would be really helpful to have a technical overview of how coyim works (maybe a diagram? ;D) so that we understand the general data flow (or where data is stored). This would cut down the time for new people who are trying to understand the system. For example: Coyim talks with an xmpp server and integrates with tor in this way...
