    Hello Jacek,

    Signing a PDF document with our RadPdfProcessing api requires a System.Security.Cryptography.X509Certificates.X509Certificate2 certificate. We have an example demonstrating how to digitally sign a PDF in our QSF examples for WPF: under PdfProcessing -> Digitally Sign Document​. In Example.xaml.cs you can see how we use a certificate stream from a file to create a X509Certificate2 and sign the document. 
    Similarly, you could detect and extract a X509Certificate2 certificate from a smart card. I've found this forum discussing how to achieve that which you might find helpful:
