In the realm of software development, code signing certificates play a pivotal role in ensuring the authenticity and integrity of code. For individual developers, obtaining these certificates involves a rigorous identity validation process. This blog explores the challenges individual developers face and how Trusted Signing can streamline the code signing process, with a focus on how its individual validation process contributes to this efficiency. 

Challenges faced by Individual Developers in Code Signing 

Individual developers often face unique challenges when it comes to code signing. Here are some key issues: 

Identity Validation process: This includes challenges such as obtaining the necessary documentation, undergoing lengthy verification processes, and dealing with differing requirements from various CAs.  

Private Key Theft or Misuse: Private keys are crucial for the code signing process and must be protected at all times. If these keys are stolen, attackers can use the compromised certificates to sign malware, distributing harmful software under a verified publisher name. It is expensive for individual developers to invest in the infrastructure and operations required to manage and store the keys. 

Complexity and Cost: The process of obtaining and managing code signing certificates can be complex and expensive, especially for individual developers and small teams. This complexity can lead to incomplete signing or not signing at all. 

Integration with DevOps: Code signing needs to be integrated with DevOps processes, tool chains, and automation workflows. Ensuring that access to private keys is easy, seamless, and secure is a significant challenge. 

Code Integrity and Security: While code signing ensures the integrity of software, it does not guarantee that the signed code is free from vulnerabilities. Hackers can exploit unregulated access to code signing systems to get malicious code signed and distributed. 

What is the Trusted Signing service?  

Trusted Signing is a comprehensive code signing service supported by a Microsoft-managed certification authority. The identity validation process is designed to be robust. Certificates are issued from Microsoft-managed CAs and are subsequently protected and serviced by providing seamless integration with leading developer toolsets. This eliminates the need for individual developers to invest in additional infrastructure and operations. 

The Importance of Identity Validation 

Identity validation is crucial for securing code signing certificates. It ensures that the individual requesting the certificate is indeed who they claim to be, thereby preventing malicious actors from distributing harmful code under the guise of legitimate software. This process builds trust among users and stakeholders, as they can be confident that the signed code is authentic and has not been tampered with. 

Process for Identity Validation with Trusted Signing 

Trusted Signing utilizes Microsoft Entra Verified ID (VID) for identity validation of individual developers. This process ensures that developers receive a VID, which is accessible through the Authenticator app, offering enhanced security, a streamlined process, and seamless integration with Microsoft Entra.  

The verification process involves the following steps:  

Submission of Government-Issued Photo ID: The first requirement is to provide a legible copy of a currently valid government-issued photo ID. This document must include the same name and address as on the certificate order. 
Biometric/selfie check: Along with the photo ID, applicants need to submit a selfie. This step ensures that the person in the ID matches the individual applying for the certificate. 
Additional Verification Steps: If the address is missing on the government issued ID card, then additional documents will be required to verify the address of the applicant. 

This is how a successfully procured VID would appear in Azure portal. 

Best Practices for a Smooth Validation Process 

To ensure a smooth and successful identity validation process, individual developers should adhere to the following best practices: 

Accurate Documentation: Ensure that all submitted documents are accurate and up-to-date and follow the guidelines. 

Stay Informed: Keep abreast of any changes in the validation requirements or processes of the CA you are working with. 

Costs of using Trusted Signing service 

Trusted Signing offers two pricing tiers starting at $9.99/month and you can pick the tiers based on your usage. Both tiers are designed to provide optimal cost efficiency and cater to various signing needs. You can find the pricing details here. The costs for identity validation, certificate lifecycle management, storing the keys securely, and signing are all included in a single SKU, ensuring accessibility and predictable expenses. 

Conclusion 

Identity validation is a critical step for individual developers seeking code signing certificates. By understanding the process, preparing in advance, and following best practices, developers can successfully navigate the validation process and secure their code signing certificates with Trusted Signing. This not only enhances the security of their software but also builds trust with users and stakeholders.
