Throughout the first set-up, individual transmits instantly its identity secret, authorized vital and also a bunch of onetime pre keys to the WhatsApp server. Nevertheless, it does not have the authority to access the exclusive keys of its users.

Initiation of the session for a chat is done with a key demand process. To initiate the session for the very first time, sender requests WhatsApp server the identification trick (I_recipient), signed secret (S_recipient), and also one-time pre key (O_recipient), WhatsApp after that revert back with all those secrets. As the one-time pre trick is supplied to the sender, it gets gotten rid of from the WhatsApp web server for ever.
