getVerifyingCertificate Method
[This feature was first implemented for MSXML 5.0.]Retrieves the certificate associated with this key used to verify a signature.
Script Syntax
var oCertificate = IXMLDSigKeyEx.getVerifyingCertificate();
Visual Basic Syntax
Set oCertificate = IXMLDSigKeyEx.getVerifyingCertificate
C/C++ Syntax
HRESULT getVerifyingCertificate (IUnknown** oCertificate);
C/C++ Syntax Using Smart Pointers
IUnknownPtr oCertificate = IXMLDSigKeyEx.getVerifyingCertificate();
Parameters
- oCertificate
- In C/C++ applications not using smart pointer classes, this is a reference to the certificate associated with the key. In all other cases, this is the certificate of the key.
Return Values
- S_OK
- The method call was successful.
- E_FAIL
- The method call failed.
Remarks
You must call this method after a signature is verified.
If the signature contains a certificate, this method returns the certificate of the key. If the signature contains no certificate, the resultant oCertificate parameter is NULL.
Example
The following example demonstrates how to validate the certificate used in the signature verification. A signed signature document containing a certificate is first verified before the certificate is validated by examining the root certificate. In any production code, a more sophisticated validation procedure should be followed.
The signed signature document is used as the input for the code examples in C/C++, JScript, and Visual Basic. The output is the same in each language.
