CODE signing certificates

Code certificate is an certificate for signing applications, code and files distributed online over the Internet. As the name suggests, the code signing certificate is intended for developers and companies to sign their software applications and code. When downloading applications from the Internet, the user can not be certain that it is the original code. By signing the application with a code signing certificate on the developer's side, the user can be sure that the application is genuine and that the code has not changed. Therefore, the integrity of the content is confirmed, otherwise the software would be marked as untrustworthy. The Code Signing certificate also includes company identification through corporate validation (OV), so the customer can easily verify that the software actually comes from the publisher who signed it. By signing the application, the developer ensures its integrity and helps develop the reputation of the software.

EV Code Signing Certificate

The Extended Validation Code signing certificate offers the highest level of security. EV Code Signing certificates resolve developers 'trustworthiness' in the Windows SmartScreen filter. For programmers developing applications for Windows 10/11 EV Code signing is the most suitable certificate. The Code EV certificate is delivered on an external hardware token, where the keys for signing applications and code are located. The USB token is sent directly by the certification authority to the applicant's address and access to the keys is protected by a PIN. A new alternative are CODE certificates located in the cloud.

From June 2023, all commercial CODE signing certificates are issued according to the new rules approved by the CA/B forum and delivered only on a secure hardware token or to a secure cloud service.

Features and Benefits of CODE signing certificates

Application security

Code Signing Certificate maintains code integrity and prevents the misuse of the SW company name to distribute counterfeit software or modify code.

Distribution support

Signed applications help increase download numbers and sales revenue. Increased trust helps expand distribution channels for your software.

Customer confidence

Signed software protects customers from malware and other malicious threats. A digital signature protects and reassures customers that the integrity of the code they have downloaded is ensured and that the program is intact, not damaged, or altered in any way. Increased trust promotes better user perception of the application.


Once downloaded, the user is sure that the code obtained actually comes from you as the publisher, which ensures the company's reputation. Code Signing Certificates allow customers to identify the author of a digitally signed code, making sure the program is from the company that is expected.

Seamless integration

The offered Code Signing certificates can be used for Windows, MacOS and iOS operating systems without any problems. All certification authorities work with companies such as Microsoft or Apple and follow their recommendations and policies for issuing certificates according to the CA/Browser Forum.

FAQ of CODE Signing Certificates

We have compiled the basic information you are most interested in.

What is a Code Signing Certificate?

When customers used to buy boxed software, they had the practical certainty that the software on the included media was genuine. They had all the information at their disposal, including a manual and contacts to the developer. With the rise of the Internet and downloading software, this has not been the case for a long time and it is necessary to secure the software so that the customer has a certainty that the program he downloaded was released by the expected developer/company and was not intentionally altered. All this is ensured by Code Signing certificates for code signing, which are used to protect software distributed via the Internet. Also called Code signing certificate or Digital signature certificate.

Example of the difference in the installation of an unsigned and signed program using a Code Signing certificate.

Podepsaný a nepodepsaný SW

By signing the code, the user is assured that the software actually came from the publisher who signed it, has not been altered or damaged since it was signed. By signing their code, developers build a trusting relationship with users.

Who needs a Code certificate?

Any software publisher that plans to distribute code or content over the Internet. Codes distributed within the company over the intranet should also be signed due to operating system policies such as Windows and MacOS. All modern systems prefer signed code to protect users and prevent the spread of malicious software.

Signing the code does not change the software. It only appends a digital signature to the application's executable file, which provides enough information to verify the identity of the signer as well as ensure that the code has not been changed later.
Digital ID signing allows content publishers, including software developers, to sign content that includes software objects, macros, device drivers, firmware images, updates, configuration files, or other types of content for secure delivery over the Internet.

What is Windows SmartScreen?

SmartScreen Reputation is a Microsoft tool that provides anonymous data from the community to ensure the user's security when downloading files from the Internet. It is an imaginary security guard in the Windows ecosystem. Only Microsoft knows the exact operation and assessment of reputation, and SmartScreen can give developers a hard time.

With a standard Code Signing certificate, the developer must build a reputation to avoid a warning screen. Once a reputation has been built, new versions of an application can be signed with the same certificate and maintain the same reputation. However, code signing certificates need to be renewed. SmartScreen does not relate a renewed certificate to an expired one. This means that reputations need to be rebuilt every new CODE Signing certificate.
For the latest Windows 10/11 operating system, the EV Code Signing certificate is the best solution! Microsoft also recommends signing with a EV Code Signing Certificate on its blog in the article - Microsoft SmartScreen & Extended Validation (EV) Code Signing Certificates.

SmartScreen notification

With the EV Code certificate for signing the code, SmartScreen Reputation does not have to solve the problem and distrust, and the application passes the reputation filter without any problems to the installation dialog, where the program’s name and publisher are displayed to the user. Obviously, an increase in reputation for SmartScreen cannot be guaranteed. If the goal is to avoid SmartScreen, the only solution is to order an EV Code signing certificate.
The Code Signing EV certificate also requires the Windows Hardware Developer Center Portal to sign kernel mode drivers.
