Certificate signing
Digitally sign a generated PDF
Create a PDF and sign it with the demo certificate during the server-side save operation.
The bundled certificate is for demonstration only. Production systems should protect private keys in an appropriate certificate store or key-management service.

What this demonstrates
Apply a certificate-backed PDF signature
A digital signature protects document integrity and identifies the certificate used during signing. Any later modification can invalidate the signature in a compatible PDF reader.
This server-side workflow is suitable for automated output such as invoices, reports, or archival documents where the signing certificate is managed by the application.
API used
SaveSettings.DigitalSignature
How it works
The controller loads the bundled PKCS#12 certificate with X509KeyStorageFlags.Exportable, assigns a DigitalSignature to SaveSettings, and exports a signed Adobe PDF.
