DRMDeconstructCertificateChain function

[The AD RMS SDK leveraging functionality exposed by the client in Msdrm.dll is available for use in Windows Server 2008, Windows Vista, Windows Server 2008 R2, Windows 7, Windows Server 2012, and Windows 8. It may be altered or unavailable in subsequent versions. Instead, use Active Directory Rights Management Services SDK 2.1, which leverages functionality exposed by the client in Msipc.dll.]

The DRMDeconstructCertificateChain function retrieves a specified certificate from a certificate chain.

Syntax


HRESULT DRMDeconstructCertificateChain(
  _In_    PWSTR wszChain,
  _In_    UINT  iWhich,
  _Inout_ UINT  *pcCert,
  _Out_   PWSTR wszCert
);

Parameters

wszChain [in]

The certificate chain.

iWhich [in]

A zero-based index specifying which certificate to retrieve.

pcCert [in, out]

The length of the retrieved certificate, in characters, plus one for a null terminator.

wszCert [out]

The certificate requested.

Return value

If the function succeeds, the function returns S_OK.

If the function fails, it returns an HRESULT value that indicates the error. Possible values include, but are not limited to, those in the following list. For a list of common error codes, see Common HRESULT Values.

E_DRM_INSUFFICIENT_BUFFER

The buffer submitted was too small to hold the returned value.

Remarks

This function allows an application to retrieve individual certificates from a chain. To determine the number of certificates available, use DRMGetCertificateChainCount.

Memory allocation and deallocation for wszCert are handled by the caller. The szChain buffer length can be obtained from the pcCert parameter by calling this function with NULL in the wszCert parameter.
