(C# UWP/WinRT) PKCS11 Discover Readers and Smart Cards / Tokens

See more PKCS11 Examples

Example showing how to discover the readers (slots) and smart cards and tokens available through a vendor's PKCS11 Cryptoki module.

Note: This example requires Chilkat v9.5.0.88 or later.

Chilkat for the Universal Windows Platform (UWP)

// 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.

Chilkat.Pkcs11 pkcs11 = new Chilkat.Pkcs11();

// Specify the vendor's Cryptoki module DLL / shared lib.
pkcs11.SharedLibPath = "aetpkss1.dll";

bool success = pkcs11.Initialize();
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;
}

// Call Discover to discover what's available.
// Indicate that we only want to return slots (readers) where tokens (smart cards) are present.
// (If the device is a USB token, such as an ePass300Auto, then by definition it has a "token" present.)
bool onlyTokensPresent = true;
Chilkat.JsonObject json = new Chilkat.JsonObject();
success = pkcs11.Discover(onlyTokensPresent,json);
if (success == false) {
    Debug.WriteLine(pkcs11.LastErrorText);
    return;
}

json.EmitCompact = false;
Debug.WriteLine(json.Emit());
