Examples

Shows how to validate and display information about each signature in a document.

auto doc = System::MakeObject<Aspose::Words::Document>(get_MyDir() + u"Digitally signed.docx");

for (auto&& signature : doc->get_DigitalSignatures())
{
    std::cout << System::String::Format(u"{0} signature: ", (signature->get_IsValid() ? System::String(u"Valid") : System::String(u"Invalid"))) << std::endl;
    std::cout << System::String::Format(u"\tReason:\t{0}", signature->get_Comments()) << std::endl;
    std::cout << System::String::Format(u"\tType:\t{0}", signature->get_SignatureType()) << std::endl;
    std::cout << System::String::Format(u"\tSign time:\t{0}", signature->get_SignTime()) << std::endl;
    std::cout << System::String::Format(u"\tSubject name:\t{0}", signature->get_CertificateHolder()->get_Certificate()->get_SubjectName()) << std::endl;
    std::cout << System::String::Format(u"\tIssuer name:\t{0}", signature->get_CertificateHolder()->get_Certificate()->get_IssuerName()->get_Name()) << std::endl;
