IOpcSigningOptions::SetSignatureMethod method (msopc.h)
Sets the signature method to use to calculate and encrypt the hash value of the SignedInfo element, which will be contained in the SignatureValue element of the signature.
HRESULT SetSignatureMethod( LPCWSTR signatureMethod );
The signature method to use.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
||The method succeeded.|
||The signatureMethod parameter is NULL.|
To access the signature method before the signature is generated, call the IOpcSigningOptions::GetSignatureMethod. To access the signature method after the signature is generated, call the IOpcDigitalSignature::GetSignatureMethod method.
When a signature is validated, the signature method is used to recalculate that value, and the recalculated value is compared to the value in the SignatureValue element in the signature markup.
