IOpcSigningOptions::GetDefaultDigestMethod method

Gets the default digest method that will be used to compute digest values for objects to be signed.

Syntax

HRESULT GetDefaultDigestMethod(
  [out, retval] LPCWSTR *digestMethod
);

Parameters

digestMethod [out, retval]

A pointer to the default digest method, or the empty string "" if a default has not been set using the SetDefaultDigestMethod method.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

This method allocates memory used by the string returned in digestMethod. If the method succeeds, call the CoTaskMemFree function to free the memory.

To set the default digest method, call the IOpcSigningOptions::SetDefaultDigestMethod method.
