PresharedKey Property of the IFPCVpnNetworkIPSecSettings Interface

The PresharedKey property gets or sets the preshared key for IPsec authentication. A preshared key is a string of text that is configured on both the VPN client and the VPN server. A preshared key provides a relatively weak authentication method. We therefore recommend that you use it only in the interim when your public key infrastructure (PKI) is being deployed to obtain computer certificates, or when a preshared key is required by VPN clients.
