How is IPsec communication negotiated between two computers?

What will be an ideal response?


When an IPsec communication begins between two computers, the computers first exchange certificates or passwords/pre-shared keys to authenticate the receiver and sender. Next, data is encrypted at the NIC of the sending computer as it is formatted into an IP packet, which consists of a header containing transmission control information, the actual data, and a footer with error-correction information.
