The logical to remember with Public , Private Keys is about 2 crypting channels.
From both sides, 2 differents Keys will operate.
Like all cryptos, one can be reverse , not the other.
But the A to B, B to A must transmit all datas, and verify them.
Look at what can be switch : ( What is surrounding ? )
Computer A , Computer B
Keys A , Key B
Private function crypto
Public function crypto
Clock from A(all in) , Clock from B(all in)
checksum A , checksum B
while you ensure no errors of receiver .
The work is all done.
It's "pair" working.
