Hey you!
Come over and help me, please. We discovered a strange key agreement protocol used on this server: ctf.fluxfingers.net:1330.
They send a curve which they use later. But we think the robots are a bit UBER-cautious and do not use the curve's P. So they first exchange their public point with a technique we could not figure out. It looks like they do not need a public key for this step.
Afterwards they use another technique to agree on a key which they ultimately use to send some encrypted password.

We need this last password to shut down the robo-factory on our way to the Oktoberfest.

Oh btw, the robots use AES-ECB for symmetric encryption.
