How does EV Code Signing work?

Extended Validation (EV) Code Signing is a specialized and highly secure form of code signing that provides the highest level of trust and authenticity to users and systems. The process of how EV Code Signing works involves stringent identity verification, certificate issuance, and code signing. Here’s a step-by-step overview of how it works:

  1. Certificate Application:
    • The process begins when a developer or organization applies for an EV Code Signing Certificate from a trusted Certificate Authority (CA) that offers EV certificates. The CA is responsible for conducting the verification process.
  2. Identity Verification:
    • The CA performs a thorough identity verification of the certificate applicant. This process includes validating the legal identity and legitimacy of the applicant, often through a combination of the following:
      • Verification of the organization’s legal documents, such as articles of incorporation or business licenses.
      • Checks to ensure the applicant is in good standing and not involved in fraudulent or illegal activities.
      • Validation of the applicant’s physical address and phone number.
      • Confirmation of the applicant’s operational existence, including its website, contact information, and business activities.
  3. Document Submission:
    • The applicant may need to submit various legal documents and proof of identity to the CA to facilitate the verification process. These documents may vary based on the CA’s requirements and the applicant’s location and legal structure.
  4. Background Checks:
    • The CA may conduct background checks, legal checks, and financial checks to verify the applicant’s credibility and authenticity.
  5. Verification Completion:
    • Once the CA is satisfied with the identity verification process, they issue the EV Code Signing Certificate to the applicant. This certificate includes a public key, which is associated with the private key held by the developer or organization for code signing.
  6. Code Signing:
    • With the EV Code Signing Certificate in hand, the developer or organization can sign their code or software. This is done using the private key corresponding to the certificate’s public key. The code signing process generates a digital signature that is appended to the code.
  7. Timestamping:
    • To ensure the long-term validity of the signed code, developers often use timestamping services provided by trusted Timestamping Authorities (TSAs). This adds a timestamp to the signed code, proving that the code existed in its signed state at a specific time. Timestamping helps prevent issues related to expired certificates.
  8. Distribution:
    • The signed and timestamped code is then distributed to end-users or customers. Users who download or install the code can verify its authenticity and integrity using the EV Code Signing Certificate and timestamp.
  9. User Experience:
    • During the code installation process, users will typically see the developer’s or organization’s name prominently displayed, along with a green address bar or other visual indicators, depending on the operating system and software used. This indicates the use of an EV certificate and provides assurance of trustworthiness.
  10. Verification:
    • Users’ systems and security software verify the digital signature and timestamp during installation. If both are valid and correspond to the EV Code Signing Certificate, the code is considered trusted and authentic, reducing the likelihood of security warnings.

Advantages of EV Code Signing

Extended Validation (EV) Code Signing offers several advantages over standard code signing certificates, primarily focused on providing the highest level of trust, security, and user confidence. Here are some of the key advantages of EV Code Signing:

Code Signing Certificates EV Code Signing Certificates
One of the most helpful types of x.509-based digital signature certificates is code signing certificates. Software companies and developers use it to certify the reliability and authenticity of their programs, drivers, and applications for users. Extended Approved Code Signing, also known as EV Code Signing, is a type of code signing certificate that requires the publisher to have their identity verified, much like the EV SSL Certificate does. The buyer of an EV Code Signing certificate must submit all the necessary identification documentation.
Additionally, it assists in maintaining the software’s integrity, much like shrink-wrapping a CD you buy from a store does to guarantee that the downloadable software hasn’t been tampered with. Additionally, to prevent any unauthorized use, the Personal details of the EV Certification Signatures are delivered individually on a hardware token.
However, if you don’t sign your program or application, it is still open to threats. For instance, a hacker may insert malicious files into your product and leave soon because your users wouldn’t be made aware that it wasn’t created by them. Upon purchasing the certificate, you will receive a USB connection (hardware token) with the Private Keys individually saved on it. As a result, this physical device functions like two-factor authentication because it is required every time you try to sign a code using an EV Code Signing Certificate, assuring that no one else gains access to your certificate without your permission.
