WebClient generates a (new random) symmetric response-key using same process as in step (1). Client encrypts the response-key (2) with the transaction key from (1) ... using AES256 or whatever preferred algorithm. Via PKI, the client asymmetrically-encrypts the transaction key (1) for the server (recipient) using Server public-key. WebIPsec uses Diffie-Hellman key exchange mechanism to exchange the keys. As far as the pre shared key is concerned, it is used during messages 5 and 6 and that is for identity establishment, not for encryption.The identity details are encrypted using the symmetric key obtained after messages 3 and 4 in phase 1.

"WebIn cryptography, a symmetric key is one that is used both to encrypt and decrypt information. This means that to decrypt information, one must have the same key that was used to encrypt it. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link. " - How are symmetric keys shared
