* this carries the following information:
* 'iam' - own hash
* 'youare' - remote hash, to verify that we are correct
* 'key' - a session key that the remote peer may use to answer
* and the own seed string
* we expect the following information to be send back:
* - 'yourip' the ip of the connection peer (we)
* - 'yourtype' the type of this peer that the other peer checked by asking for a specific word
* and the remote seed string
*
