(Mono C#) PKCS11 Sign PDF with Smart Card with 2 PINsSee more PKCS11 ExamplesShows how to sign a PDF using a smart card that has one pin for USER, and a 2nd PIN for signing. Note: This example requires Chilkat v9.5.0.96 or later.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.
