The process of standard code signing involves obtaining a digital certificate from a trusted certificate authority (CA), such as GlobalSign, DigiCert, or Certum. This certificate contains information about the software publisher, including their name and contact details. The certificate is used to sign the software, which generates a unique hash value that is included with the software package.
Before signing the software, it is important to ensure that it meets all code signing requirements, such as complying with industry standards, using reputable software development tools, and avoiding the use of obsolete code libraries that may contain vulnerabilities.
Once the software has been signed, users can verify the digital signature and confirm the authenticity of the software by checking the certificate information and comparing the hash value with the one provided by the publisher.
While standard code signing provides a basic level of security and verification, it does not offer the same level of trust and assurance as EV Code Signing. This is because standard code signing does not require the same level of authentication and validation processes as EV Code Signing, as we will explore in the next section.
The Benefits of EV Code Signing
Extended Validation (EV) Code Signing offers several benefits over the standard code signing method.
One of the key advantages of EV Code Signing is its ability to enhance security and build user trust. An EV Code Signing certificate displays the software publisher’s identity prominently during installation, providing users with clear evidence that the software is authentic and has not been tampered with. It provides instant SmartScreen reputation and avoids that nasty Microsoft warnings during installation of new software, This increases user confidence and reduce the risk of users downloading malware or other harmful software.
In addition, EV Code Signing certificates typically have higher validation requirements than standard certificates. This means that the issued certificate undergoes a more rigorous authentication process, providing a higher level of assurance regarding the identity of the software publisher.
EV Code Signing certificates are also recognized and trusted by a wider range of platforms and operating systems, making them a more versatile option for developers.
Overall, EV Code Signing provides a more robust and trustworthy method of signing software, communicating the legitimacy of the software to users and building more secure applications.
Code Signing Best Practices
Code signing is a critical process for securing software, and following best practices is essential for ensuring its efficacy. Here are some key considerations:
- Use reputable certificate authorities: Only use established and trusted certificate authorities to issue code signing certificates. This ensures that the certificate is recognized and accepted by most platforms and operating systems.
- Keep certificates up to date: Certificates have a limited lifespan, so it’s essential to renew them regularly to ensure the integrity and security of your software.
- Protect your private key: The private key used to sign your code is the key to the security of your software. Keep your token safe and secure to prevent unauthorized access.
- Always timestamp your signatures: Timestamping ensures that your signatures remain valid even after your certificate has expired.
- Follow proper security procedures: Protect your development environment and signing process from unauthorized access. Use strong passwords, two-factor authentication, and hardware security tokens to safeguard your code signing process.
By following these best practices, you can ensure that your code signing process is effective and secure, protecting your software and your users from potential security risks.
Industry Standards for Code Signing
Code signing is subject to industry standards which outline the requirements for the digital certificates used to sign software. These standards are in place to ensure interoperability and the highest level of security and trust among all signing parties. To that end, leading industry standards include:
| Standard | Description |
|---|---|
| Extended Validation Code Signing (EV Code Signing) | A high-assurance digital certificate requiring a rigorous validation process that includes verification of the organization’s legal and operational existence, as well as its control of the domain used for signing. |
| Standard Code Signing | A digital certificate that verifies the identity of the software publisher and the integrity of the code. These certificates may be issued with more or less validation, depending on the certificate authority (CA). |
| Microsoft Authenticode | Microsoft’s specific implementation of code signing standards, which requires a digital certificate from a trusted CA to verify the publisher’s identity. |
While the specific requirements for each standard may vary slightly, they all adhere to the fundamental principle of ensuring the integrity and authenticity of digital signatures. Therefore, it is important to choose the appropriate code signing option that meets industry standards and aligns with the specific security requirements of the software being signed.
