FpcVpnDiffieHellmanGroup enumeration

  • Article

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;

Constants

  • fpcVpnDHGroup1
    Diffie-Hellman Group 1, which provides a keying strength of 768 bits.

  • fpcVpnDHGroup2
    Diffie-Hellman Group 2, which provides a keying strength of 1,024 bits.

  • fpcVpnDHGroup2048
    Diffie-Hellman Group 2048, which provides a keying strength of 2,048 bits.

  • fpcVpnDHECPGroup256
    Diffie-Hellman 256-bit Random ECP Group.

  • fpcVpnDHECPGroup384
    Diffie-Hellman 384-bit Random ECP Group.
