Return value
If the method succeeds, it returns S_OK; otherwise, it returns an HRESULT error code.
Remarks
The digest method must be set before signing.
When a new instance of this interface is returned by IXpsSignatureManager::CreateSigningOptions, the SignatureMethod and DigestMethod properties are not valid; they must be initialized before the new interface can be used as a parameter of the Sign method.
This method allocates the memory used by the string that is returned in digestMethod. If digestMethod is not NULL, use the CoTaskMemFree function to free the memory.
