Phase2DHGroup Property of the IFPCVpnNetworkIPSecSettings Interface
The Phase2DHGroup property gets or sets a value from the FpcVpnDiffieHellmanGroup enumerated type that specifies the Diffie-Hellman group to be used in Phase 2 of the IPsec negotiation process.
C++
HRESULT put_Phase2DHGroup(
FpcVpnDiffieHellmanGroup Phase2DHGroup
);
HRESULT get_Phase2DHGroup(
FpcVpnDiffieHellmanGroup* pPhase2DHGroup
);
Parameters
Phase2DHGroup
Value from the FpcVpnDiffieHellmanGroup enumerated type that specifies the Diffie-Hellman group to be used in Phase 2 of the IPsec negotiation process.pPhase2DHGroup
Pointer to a value from the FpcVpnDiffieHellmanGroup enumerated type that is set on return to the value specifying the Diffie-Hellman group to be used in Phase 2 of the IPsec negotiation process.
Return Value
These property methods return S_OK if the call is successful; otherwise, they return an error code.
Visual Basic
Property Phase2DHGroup As FpcVpnDiffieHellmanGroup
Property Value
Value from the FpcVpnDiffieHellmanGroup enumerated type that specifies the Diffie-Hellman group to be used in Phase 2 of the IPsec negotiation process.
Remarks
This property is read/write. Its default value is fpcVpnDHGroup2, which specifies Diffie-Hellman Group 2.
The Diffie-Hellman group sets the length of the base prime numbers used during the key exchange process. The cryptographic strength of any key derived depends, in part, on this length.
