Load Certificate from Smart Card by Serial Number

See more Certificates Examples

This example requires Chilkat v9.5.0.87 or greater. It uses a Windows-only function named LoadFromSmartcard.

This example loads a certificate specified by its hexidecimal serial number. The LoadFromSmartcard method will examine the connected smart cards and USB tokens and will find and load the certificate having the specified serial number.

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.

    const cert = try chilkat.Cert.init();
    defer cert.deinit();

    // If you know the smart card PIN, set it prior to loading from the smartcard/USB token.
    cert.setSmartCardPin("12345678");

    // To load the certificate specified by its hexidecimal serial number, pass the string "serial=<hexSerialNumber>".  For example:
    cert.loadFromSmartcard("serial=4A1E6ADCF59DB1EFBAAE438D2C52664E40D16A87") catch {
        std.debug.print("{s}\n", .{try cert.getLastErrorText(alloc)});
        std.debug.print("Certificate not loaded.\n", .{});
        return;
    };

    std.debug.print("Found: {s} serial={s}\n", .{ try cert.getSubjectDN(alloc), try cert.getSerialNumber(alloc) });

    // Here's another example.
    // Note: serial numbers can be of different lengths.  The length of the serial number depends on the certificate.
    const cert2 = try chilkat.Cert.init();
    defer cert2.deinit();
    cert2.loadFromSmartcard("serial=66BE58138D761E92BC594A722932657BE26D421F") catch {
        std.debug.print("{s}\n", .{try cert2.getLastErrorText(alloc)});
        std.debug.print("Certificate not loaded.\n", .{});
        return;
    };

    std.debug.print("Found: {s} serial={s}\n", .{ try cert2.getSubjectDN(alloc), try cert2.getSerialNumber(alloc) });
