Hello,
I'm looking for the feature "Protection and encryption" but I can not find it in the demo nor in the documentation.
Is it possible to sign a pdf document in UWP as does Adobe Reader?
Signing with a certificate currently is not supported, you can implement (not-graphometric and not-certified) signature using PDFAnnot.SetIcon for example.
We support password-protected documents, and encryption and decryption (3DES, AES128, AES256).
