+## Integrating signature and timestamp certificates into the Document Secure Store (DSS).
+
+Effortlessly Integrate **signature and timestamp** certificates into the Document Security Store (DSS) with the Essential PDF Library. This streamlined process enhances certificate management, ensuring robust validation for your PDF documents. Below is a code example demonstrating how to include certificates when creating Long-Term Validity (LTV) from an external signature, utilizing the [CreateLongTermValidity](https://help.syncfusion.com/cr/file-formats/Syncfusion.Pdf.Security.PdfSignature.html#Syncfusion_Pdf_Security_PdfSignature_CreateLongTermValidity_System_Collections_Generic_List_System_Security_Cryptography_X509Certificates_X509Certificate2__System_Boolean_) method in the [PdfSignature](https://help.syncfusion.com/cr/file-formats/Syncfusion.Pdf.Security.PdfSignature.html) class.
