Validate a Smartcard PIN

See more Certificates Examples

Validates a smartcard PIN. This example only runs on Windows and requires Chilkat v9.5.0.77 or greater. Zig

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

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

    // Note: Requires Chilkat v9.5.0.77 or greater.

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

    cert.setSmartCardPin("000000");

    // Load the certificate on the smartcard currently in the reader (or on the USB token).
    // Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
    // See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
    cert.loadFromSmartcard("") catch {
        std.debug.print("{s}\n", .{try cert.getLastErrorText(alloc)});
        return;
    };

    // Check to see if the SmartCardPin property contains the valid PIN for the smartcard.
    const pin_valid = cert.checkSmartCardPin();
    if (pin_valid < 0) {
        std.debug.print("Unable to check the PIN validity.\n", .{});
        std.debug.print("{s}\n", .{try cert.getLastErrorText(alloc)});
        return;
    }

    if (pin_valid == 1) {
        std.debug.print("PIN is valid.\n", .{});
    } else {
