GetCertificate function

Returns a certificate that the display miniport driver uses for either the cryptographic session certificate or authenticated channel.


VOID APIENTRY* GetCertificate(
  _In_   D3D10DDI_HDEVICE hDevice,
  _In_   const D3D11_1DDI_CERTIFICATE_INFO *pCertificateInfo,
  _In_   UINT CertificateSize,
  _Out_  BYTE *pCertificate


hDevice [in]

A handle to the display device (graphics context).

pCertificateInfo [in]

A pointer to a D3D11_1DDI_CERTIFICATE_INFO structure that specifies the cryptographic session certificate or authenticated channel to return.

CertificateSize [in]

The size, in bytes, of the buffer that is referenced by the pCertificate parameter.

pCertificate [out]

A pointer to a byte array that receives the driver's certificate chain.

Return value

This function does not return a value.


Based on the data in the D3D11_1DDI_CERTIFICATE_INFO structure, GetCertificate returns the certificate for either the cryptographic session or the authenticated channel. The driver uses this certificate to establish trust and perform key exchange for the session or channel.

Note  The size, in bytes, of a driver's certificate chain can be queried by calling GetCertificateSize.
