FpcVpnDiffieHellmanGroup enumeration
Applies to: desktop apps only
The FpcVpnDiffieHellmanGroup enumerated type contains values that specify the Diffie-Hellman groups that can be used in Phase 1 or Phase 2 of the Internet Protocol security (IPsec) negotiation process. 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.
Syntax
typedef enum FpcVpnDiffieHellmanGroup {
fpcVpnDHGroup1 = 0,
fpcVpnDHGroup2 = 1,
fpcVpnDHGroup2048 = 2,
fpcVpnDHECPGroup256 = 3,
fpcVpnDHECPGroup384 = 4
} FpcVpnDiffieHellmanGroup;
