What is code signing

Code signing is the process of digitally signing executable or script files to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The signature also serves as a means of identifying the software publisher. Code signing can provide end users with the assurance that the code they receive has not been tampered with and that it was produced by a trusted source. Additionally, many operating systems, such as Microsoft Windows and Apple's macOS, will give a warning or prevent the execution of unsigned code, making code signing a necessary step for software distribution on those platforms.

How to sign windows Electron Application

To sign a Windows Electron application, you will need to use a code signing certificate. Here is a general overview of the process:

1. Obtain a code signing certificate: You can purchase a code signing certificate from a trusted certificate authority (CA) such as DigiCert, GlobalSign, or Comodo.

2. Sign your application: Use the signtool.exe utility that comes with the Microsoft SDK to sign your executable. You can use the following command to sign your application:

bash
signtool.exe sign /f <path-to-certificate-file> /p <certificate-password> /t http://timestamp.digicert.com <path-to-executable>

3. Verify the signature: You can use the following command to verify the signature of your application:

bash
signtool.exe verify /pa <path-to-executable>

4. Timestamp your signature: You can use the following command to timestamp your signature:

bash
signtool.exe sign /f <path-to-certificate-file> /p <certificate-password> /tr http://timestamp.digicert.com /td sha256 <path-to-executable>

5. Package your application: After signing and timestamping the application, you need to package the application. You can use electron-builder to package your application.

Please note that this is just a general overview and you might need to refer to the official documentation of the tool you use and the certificate authority you obtained the certificate from for more detailed instructions.

Benefits of code signing process

Code signing provides several benefits, including:

1. Authentication: Code signing verifies the identity of the software publisher, providing end users with a way to verify that the code they are receiving is from a trusted source.

2. Integrity: Code signing uses a cryptographic hash to ensure that the code has not been tampered with or altered since it was signed. This provides end users with the assurance that the code they are receiving is the same code that was originally published by the software publisher.

3. Non-repudiation: Code signing creates a digital signature that cannot be denied or repudiated by the software publisher. This provides end users with legal evidence that the code they received was indeed published by the software publisher.

4. Increased security: Code signing can help prevent malware and other malicious code from being distributed. Many operating systems will give a warning or prevent the execution of unsigned code, making it more difficult for attackers to distribute malware.

5. Improved user experience: Code signing can help improve the user experience by providing users with the assurance that the code they are receiving is from a trusted source and has not been tampered with, which can help to increase user trust and confidence in the software.

6. Legal protection: Code signing can provide legal protection to software publishers by providing evidence of authorship and integrity.

Please note that code signing does not ensure that the code is free from vulnerability or malware but it ensures the authenticity of the software publisher and the integrity of the code.

Useful Resources

There are several important resources that can help you learn more about code signing and how to implement it in your own projects. Here are a few:
