Authenticode Sign using Smartcard or USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a smartcard or USB token, such as a Yubikey.

Note: Chilkat's code signing class was added in v9.5.0.97

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 create the following JSON to specify that SHA256 is to be used,
    // and provide timestamp server information.

    // {
    //   "hashAlg": "sha256",
    //   "timestampToken": {
    //     "enabled": true,
    //     "tsaUrl": "http://timestamp.digicert.com",
    //     "requestTsaCert": true,
    //     "hashAlg": "sha256"
    //   }
    // }

    const json = try chilkat.JsonObject.init();
    defer json.deinit();
    json.updateString("hashAlg", "sha256") catch {};
    json.updateBool("timestampToken.enabled", true) catch {};
    json.updateString("timestampToken.tsaUrl", "http://timestamp.digicert.com") catch {};
    json.updateBool("timestampToken.requestTsaCert", true) catch {};
    json.updateString("timestampToken.hashAlg", "sha256") catch {};

    // The only difference in signing with a smartcard or USB token
    // is that the cert is loaded from a smartcard or USB token, instead of a PFX or from elsewhere
    // such as from the Windows certificate store.
    const cert = try chilkat.Cert.init();
    defer cert.deinit();

    // Yubico YubiKey OTP+FIDO+CCID 0, default PIN = 123456
    cert.setSmartCardPin("123456");

    // Assuming you have the Yubikey inserted into the USB on the computer...
    // and there is only 1 signing certificate on the Yubikey, then just load from
    // the "smartcard".  (assuming you don't have additional smartcards or USB tokens plugged in)
    cert.loadFromSmartcard("") catch {
        std.debug.print("{s}\n", .{try cert.getLastErrorText(alloc)});
        return;
    };

    // If the smartcard/token has several possible certificates that can be used for signing,
    // then see the online documentation for the LoadFromSmartcard method,
    // and also see the online documentation and examples for Chilkat Pkcs11 and ScMinidriver.
    // There are many possible ways to load a Chilkat certificate object with a cert (and associated private key)
    // from a variety of sources.  The only coding difference for any signing function in Chilkat,
    // whether it be a PDF, XmlDSig, CMS, etc. is in how the cert is loaded.

    // You can sign .exe or .dll files.
    const exe_path = "C:/someOtherDir/HelloWorld.exe";

    const signer = try chilkat.CodeSign.init();
    defer signer.deinit();

    // If successful, the following call will apply the signature to the EXE (or DLL).
    signer.addSignature(exe_path, cert, json) catch {
        std.debug.print("{s}\n", .{try signer.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("Successfully applied the Authenticode signature.\n", .{});
