Gather Smartcard Debug Information for Chilkat

See more ScMinidriver Examples

This example demonstrates how to gather information to send to support@chilkatsoft.com about your smartcard. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // First, Chilkat recommends downloading the MGTEK Smartcard Minidriver Tool to get information
    // about your smartcard.

    // The tool can be downloaded from https://www.mgtek.com/smartcard

    // --------------------------------------------------------------------------------------------------------
    // 1. Select the smartcard as shown below and send Chilkat a screenshot of the basic smartcard information.
    // --------------------------------------------------------------------------------------------------------
    //
    // (image:https://example-code.com/images/mgtek_screenshot.jpg/endImage)
    //
    // --------------------------------------------------------------------------------------------------------
    // 2. Select the cmapfile (if present) as shown below and send Chilkat a screenshot of the CSP container map
    // --------------------------------------------------------------------------------------------------------
    //

    // ---------------------------------------------------------
    // Chilkat provides functions to get information about the smartcard, and what it contains.
    // Send Chilkat the output of the following source code:

    const scmd = try chilkat.ScMinidriver.init();
    defer scmd.deinit();

    // Reader names (smart card readers or USB tokens) can be discovered
    // via PCSC List Readers or PCSC Find Smart Cards
    const reader_name = "Alcor Micro USB Smart Card Reader 0";
    scmd.acquireContext(reader_name) catch {
        std.debug.print("{s}\n", .{try scmd.getLastErrorText(alloc)});
        return;
    };

    const json = try chilkat.JsonObject.init();
    defer json.deinit();
    json.setEmitCompact(false);

    // ------------------------------------------------------
    // 3. Send Chilkat the JSON returned by GetCardProperties
    // ------------------------------------------------------
    scmd.getCardProperties(json) catch {
        std.debug.print("{s}\n", .{try scmd.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("{s}\n", .{try json.emit(alloc)});

    // ------------------------------------------------------
    // 4. Send Chilkat the JSON returned by GetCspContainerMap
    // ------------------------------------------------------
    json.clear();
    scmd.getCspContainerMap(json) catch {
        std.debug.print("{s}\n", .{try scmd.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("{s}\n", .{try json.emit(alloc)});
