During the initial set-up, individual transmits immediately its identity trick, authorized key and a lot of onetime pre secrets to the WhatsApp web server. However, it does not have the authority to access the exclusive keys of its customers.

Initiation of the session for a chat is done via a vital demand procedure. To launch the session for the very first time, sender demands WhatsApp server the identity trick (I_recipient), authorized trick (S_recipient), and also one-time pre trick (O_recipient), WhatsApp then change back with all those secrets.

ECDH(I_initiator,S_recipient) ||ECDH(E_initiator,I_recipient)||
ECDH(E_initiator,S_recipient) ||ECDH(E_initiator,O_recipient)

Code Generation Refine


In a similar way, HKDF code is used to create chain & root tricks from the Master Key code by both the initiator as well as the recipient during each time of message exchange. Now the recipient can send out message to the sender at it will be immediately gotten at the various other end irrespective of the on-line standing of recipient.
