2. You’re pc creates a request (“hey, present me what fb has”)
3. You’re already linked to the VPN so your request to fb goes to the VPN server you might be linked to as a substitute of on to fb.
4. The VPN server is like. oh god one other request for fb lets ahead this to the exit node ( the server the place your requests will seem to come back from )
5. The exit node generates a (hey fb, present me what you bought) message and sends it to fb
6. Fb is like oh somebody needs to see my stuf, nicely if you wish to speak to me it’s important to be encrypted, heres how you can encrypt knowledge for me (sends a key to encrypt knowledge)

13. The VPN server is aha an encypted message for me lets un encrypt it. Ah that is an encrypted message for fb! ship it to the exit level
14. The exit level will get the forwarded message and sends it to fb (nonetheless encrypted as fb will decrypt the message with their non-public decryption key)
15. Congratulations your request to fb simply went by way of the vpn and was encrypted all the way in which there. Fb will now create an encrypted message for you.
16. The message is shipped from fb to the exit node.
17. The exit node encrypts it with the VPN encryption key (double encrypted once more)
18. The message is shipped to the entry node
