Code Signing using Sectigo USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a SafeNet USB token from Sectigo.

Requires Chilkat v10.0.0 or greater.

Objective-C

#import <CkoJsonObject.h>
#import <CkoCert.h>
#import <NSString.h>
#import <CkoCodeSign.h>

BOOL success = NO;

//  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"
//    }
//  }

CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json UpdateString: @"hashAlg" value: @"sha256"];
[json UpdateBool: @"timestampToken.enabled" value: YES];
[json UpdateString: @"timestampToken.tsaUrl" value: @"http://timestamp.digicert.com"];
[json UpdateBool: @"timestampToken.requestTsaCert" value: YES];
[json UpdateString: @"timestampToken.hashAlg" value: @"sha256"];

//  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.
CkoCert *cert = [[CkoCert alloc] init];

//  Use your USB token PIN (user password).
//  It will be a string similar to this:  j6X54nB7-jlp5Cr2
cert.SmartCardPin = @"j6X54nB7-jlp5Cr2";

//  Load the certificate based on the serial number.
//  *** Use your certificate's serial number.
success = [cert LoadFromSmartcard: @"serial=3FF5B69109BFD4046C92CC0D18EE23C2"];
if (success == NO) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

//  Note: If the above fails, then use the SafeNet Authentication Client Tools
//  to login to your token using your token password.
//  You don't want too many failed logins, otherwise you'll lock the token.
//  A successful login will reset number of failed logins back to 0.

//  Note: This is to sign Microsoft Windows executables or DLLs
//  You can sign .exe or .dll files.
NSString *exePath = @"C:/someDirectory/HelloWorld.exe";

CkoCodeSign *signer = [[CkoCodeSign alloc] init];

//  If successful, the following call will apply the signature to the EXE (or DLL).
success = [signer AddSignature: exePath cert: cert options: json];
if (success == NO) {
    NSLog(@"%@",signer.LastErrorText);
    return;
}

NSLog(@"%@",@"Successfully applied the Authenticode signature.");
