I use my private key AND your public key. I put both of them into a algoritm. The output from that is a static password. This password do I use to encrypt all traffic I will send to you, and I will use the same password to decrypt all received traffic. When you take YOUR private key and MY public key and put them into the same algoritm You will get the same static password. So, in practice, all traffic is encrypted/decrypted in both ends by the same "pre-shared-key". The only thing with PKI is that our combinations of private and public keys makes it unneccesary to ever exchange this pre-shared-key. Instead it is derived from our public and private keys. Br Jimmy
