Phase1Integrity Property of the IFPCVpnNetworkIPSecSettings Interface

Article
08/13/2010

The Phase1Integrity property gets or sets a value from the FpcVpnIntegrityAlgorithm enumerated type that specifies the integrity algorithm to be used in Phase 1 of the IPsec negotiation process. The possible algorithms are the Message Digest 5 (MD5) integrity algorithm, which uses a 128-bit key, and the Secure Hash Algorithm 1 (SHA1) integrity algorithm, which uses a 160-bit key.

C++

HRESULT put_Phase1Integrity(
    FpcVpnIntegrityAlgorithm Phase1Integrity
);
HRESULT get_Phase1Integrity(
    FpcVpnIntegrityAlgorithm* pPhase1Integrity
);

Parameters

Phase1Integrity
Value from the FpcVpnIntegrityAlgorithm enumerated type that specifies the integrity algorithm to be used in Phase 1 of the IPsec negotiation process.
pPhase1Integrity
Pointer to a value from the FpcVpnIntegrityAlgorithm enumerated type that is set on return to the value specifying the integrity algorithm to be used in Phase 1 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 Phase1Integrity As FpcVpnIntegrityAlgorithm

Property Value

Value from the FpcVpnIntegrityAlgorithm enumerated type that specifies the integrity algorithm to be used in Phase 1 of the IPsec negotiation process.

Remarks

This property is read/write. Its default value is fpcVpnSHA1, which specifies the SHA1 integrity algorithm.
