About EV Code Signing

Code signing certificates are used by software developers to digitally sign a program to prove that it has not been altered or compromised by a third party. While software purchased from a retail store is typically considered to be relatively safe, programs downloaded from the Internet are often treated with suspicion because of the widespread proliferation of viruses and malware. With a certificate from a trusted Certificate Authority like DigiCert, you can prevent unnecessary warning messages and protect your software from malware, tampering, and theft.

Code that is signed with an EV certificate establishes your reputation and reduces warning messages with Microsoft’s SmartScreen® Application Reputation filter–instilling trust in end-users. And, because of DigiCert’s partnership with Microsoft, our certificates give you an immediate reputation in Windows® 8, 8.1, and 10, Internet Explorer® 9, 10, and 11, and Microsoft Edge®. Our certificates are also compatible with Windows Mobile, Authenticode, Kernel Mode, Office, VBA, Java, Adobe, and more.

How it Works

To sign code, you must first purchase a code signing certificate and download a code signing ‘engine’ suitable for your operating system. Using the code signing engine, you select the code that you want to sign and sign it with your certificate token. With an EV certificate, the token is stored on a USB device that is provided when you purchase your certificate. The code is then signed and will contain a timestamp as well as your company’s information so that users know where the code is from and that it hasn’t been tampered with. With an EV certificate, this stamp will also let Microsoft’s SmartScreen filter know that the code is secure.

The benefit to having an EV code signing certificate is that your certificate token is stored on an external USB device. This means that only people with the physical device can sign code with your certificate—the certificate doesn’t live on your machine and isn’t exportable.

Protect Your Customers

Code signing certificates allow you to digitally sign code, indicating to users that it has not been tampered with and that its authenticity has been verified. Extended validation code signing provides a rigorous vetting process combined with a hardware security requirement so that your users can have even greater confidence in the integrity of your applications.

Meet the Requirements of Your Partners

Your partners and distribution channels want to ensure that they are not risking their reputation and their customers’ safety by distributing your code. Digital signatures allow them to verify that the content they are sharing is legitimate.

Increase Confidence

With the looming danger of downloading malware, users are very cautious of downloaded software. EV code signing certificates from DigiCert follow the highest authentication standards, helping to instill users’ trust in you as a publisher and in your programs. After all of the efforts you put into developing your code, enjoy the peace of mind that comes from your authentication having been validated by a name that is trusted for high assurance.

Increase Security

EV code signing certificates from DigiCert provide added security against malware, tampering, and theft by storing your certificate’s private key on a secure hardware token. This hardware is used during the signing process and adds an extra layer of security to help protect the integrity of your code.

Simplify Monitoring and Enforcement

A digital signature helps identify the authenticity of signed code, making it easy to screen for modified files. With a DigiCert time stamp, any signed code remains valid even after the code signing certificate expires and users can tell that the code was signed with a valid certificate.

Protect Your Reputation

Consumers expect a smooth installation process and warning messages look unprofessional and create suspicion. Code signing allows you to forgo these types of messages and trains your customers to only trust digitally-signed code.

Increase Adoption

Because of the proliferation of malware disguised as legitimate software, many consumers are extremely suspicious of any software downloaded from the web. Unexpected warning messages from their OS or browser, no matter how benign, can cause users to cancel an installation. However, with a DigiCert certificate your code will be trusted by many operating systems and browsers, allowing users to complete the installation and use the software with confidence.

Establish Reputation with Microsoft's SmartScreen® Filter

Programs signed by an EV code signing certificate can immediately establish reputation with Microsoft SmartScreen reputation services—even if no prior reputation exists for that file or publisher. Now, even brand new publishers have and benefit from an immediate reputation.
