HashAlgorithmId Property of the IFPCCookieCryptoConfiguration Interface

Article
08/13/2010

The HashAlgorithmId property gets or sets the identifier of the algorithm used for cookie hashing.

C++

HRESULT put_HashAlgorithmId(
    long lHashAlgorithmId
);
HRESULT get_HashAlgorithmId(
    long* plHashAlgorithmId
);

Parameters

lHashAlgorithmId
A 32-bit integer that specifies the identifier of the algorithm used for cookie hashing.
plHashAlgorithmId
Pointer to a 32-bit integer that is set on return to the identifier of the algorithm used for cookie hashing.

Return Value

These property methods return S_OK if the call is successful; otherwise, they return an error code.

Visual Basic

Property HashAlgorithmId As Long

Property Value

A 32-bit integer that specifies the identifier of the algorithm used for cookie hashing.

Remarks

This property is read/write. The default value is the hexadecimal number 800C, which is the identifier of Secure Hash Algorithm 256 (SHA-256). This algorithm produces a 256-bit hash.

The ALG_ID data type specifies an algorithm identifier. Values of this data type are passed to most of the functions in the CryptoAPI. For the identifier values used for specific algorithms , see ALG_ID.

Requirements

Client	Requires Windows 7 or Windows Vista.
Server	Requires Windows Server 2008 R2 or Windows Server 2008 x64 Edition with SP2.
Version	Requires Forefront Threat Management Gateway (TMG) 2010.
IDL	Declared in Msfpccom.idl.
DLL	Requires Msfpccom.dll.
