The Phase1DHGroup property gets or sets a value from the FpcVpnDiffieHellmanGroup enumerated type that specifies the Diffie-Hellman group to be used in Phase 1 of the IPSec negotiation process.
HRESULT get_Phase1DHGroup( FpcVpnDiffieHellmanGroup* pPhase1DHGroup ); HRESULT put_Phase1DHGroup( FpcVpnDiffieHellmanGroup Phase1DHGroup );
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.
The value fpcVpnDHGroup2048, which specifies Diffie-Hellman Group 2048, is not supported on computers running a Windows 2000 Server operating system.
