System::String Aspose::Words::DigitalSignatures::DigitalSignature::get_IssuerName()

Examples

Shows how to sign documents with X.509 certificates.

// Verify that a document is not signed.
ASSERT_FALSE(FileFormatUtil::DetectFileFormat(MyDir + u"Document.docx")->get_HasDigitalSignature());

// Create a CertificateHolder object from a PKCS12 file, which we will use to sign the document.

// There are two ways of saving a signed copy of a document to the local file system:
// 1 - Designate a document by a local system filename and save a signed copy at a location specified by another filename.

// 2 - Take a document from a stream and save a signed copy to another stream.
