Phase1Encryption Property of the IFPCVpnNetworkIPSecSettings Interface

The Phase1Encryption property gets or sets a value from the FpcVpnEncryptionAlgorithm enumerated type that specifies the encryption algorithm to be used in Phase 1 of the IPsec negotiation process. The possible algorithms are the Data Encryption Standard (DES) algorithm, which uses a 56-bit key, and the Triple Data Encryption Standard (3DES) algorithm, which uses three 56-bit keys.

[C++]

HRESULT put_Phase1Encryption(
	FpcVpnEncryptionAlgorithm Phase1Encryption
);
HRESULT get_Phase1Encryption(
	FpcVpnEncryptionAlgorithm* pPhase1Encryption
);

Parameters

pPhase1Encryption: Pointer to a value from the FpcVpnEncryptionAlgorithm enumerated type that is set on return to the value specifying the encryption algorithm to be used in Phase 1 of the IPsec negotiation process.
Phase1Encryption: Value from the FpcVpnEncryptionAlgorithm enumerated type that specifies the encryption 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 Phase1Encryption As FpcVpnEncryptionAlgorithm

Property Value

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

Remarks

This property is read/write. Its default value is fpcVpn3DES, which specifies the 3DES algorithm.
