What is Visual Studio Code Signing Certificate [A Detailed Guide]

Code signing is essential to securing a program and authenticating its originality. Every cybercrime attack leads to a loss of $197 per individual. In this instance, you cannot blame the users if they are extra cautious before downloading your software.

Visual Studio code signing certificate is of the methods to secure your software. A digitally signed software enjoys a higher level of trust and security. Hence, the users are comfortable with downloading the software or executable files from the web.

In a scenario where people are regularly becoming victims of cybercrime, a code signing certificate is not a big ask from your potential customers. They need to know that the software they are about to download is safe and won’t land them into any sort of trouble.

Code signing certificate can be obtained with Visual Studio, and in this article, we are going to discuss the process for the same.

What are the Benefits?

Code signing is essential for a developer or a development company, and it is required for two types of confirmation. One, it provides proof for the author/developer of the software or application. Second, it provides evidence that there is no code tampering after signing.

Better Distribution and Revenue:

The ever-increasing trend of using mobile applications and software proliferation makes code signing necessary. Due to this, software publishers also require developers and development companies to get code signing certificates from a trusted source. This ultimately helps with smoother distribution and higher revenue.

Protects Code Integrity:

After you Get Visual Studio Code Signing Certificate, it locks your source code in its final stage. In most cases, the certificate creates a hash of the entire code. During the download process, if the hash value matches the original hash value generated, it means that the code integrity is intact. A different hash value is proof of code tampering.

In addition to this, a code signing certificate also protects the developers from fraud and code tampering.

Better Security and Trust:

While downloading software, the users are asked to trust the software and move ahead with the download process. In this scenario, software with a signed certificate is easier to trust. This is because the Code Signing Certificate provides the required security to the solution making it more trustworthy and reliable.

Code Signing Certificate is one of the ways to boost software adoption and garner customers’ trust. Customers today are more aware of the risks in the web world and want to tread securely.

What is Visual Studio?

Visual Studio Code is an interface within Visual Studio, and this component is a dedicated source code editor. The developers can access powerful editing tools and get access to IntelliSense code completion features. Other features include debugging, code navigation, refactoring, version control, etc.

The basic purpose of VS Code is to allow developers to edit, build, and debug quickly. It supports hundreds of programming languages so that you can work seamlessly.

While using VS Code, you will experience heightened productivity because of its many functions, including;

• Syntax highlighting
• Bracket matching
• Auto indentation
• Snippets
• Box selection

These and many other such functions makes working with VS Code straightforward and highly productive. It’s software that understands your code and helps you in a way that you end up building a highly professional and performant solution.

VS Code has an interactive debugger. This helps developers to meticulously go through every line of code and inspect variables, view all call stacks, and even execute commands in the console. On the whole, VS Code not only improves the coding experience but also fastens the process.

How to Sign Authenticode files with Visual Studio?

Code signing is one part of the exercise; another important element of the same process is the Certificate Authority (CA). Obtaining the certificate from a trusted CA is just as important as getting the certificate.

If you are publishing without a certificate or publishing with a certificate from an untrustworthy source, the result will be equally risky. Hence, we recommend that you obtain the certificate from a trusted source.

To sign your software with a certificate, follow these steps;

1. Obtain the Certificate:

The first step is to obtain the certificate from a trusted source. There are a lot of CAs out there, so make sure to associate with the right ones. Look for these signs;

• The CA should be a thought leader. In other words, the CA you wish to deal with must play a key role in developing the baseline standards. It must have active involvement in the industry groups and offers recommendations for best practices, compliance, and certificate management.

2. Select Project Properties:

First open Project Properties. Right-click on the project from the Solution Explorer tab and click on Properties.

3. Select Certificate:

From properties, click the Signing Tab and navigate to Sign the ClickOnce manifests. From here, select the certificate from the Windows Certificate Store.

4. Timestamp Server:

After selecting the certificate, you can move ahead and add the time stamp server. To add this, look for the Timestamp Server in the URL box and add it there.

This process is for the VS Code signing when choosing the certificate from a Windows Store. How to go about it when you have an existing file?

Follow this process for the second option.

1. Get to the Signing Page:

Follow the same steps as above until you reach the signing page.

2. Select File:

Once on the Signing page, go to the ClickOnce manifests tick box and click on Select from File option. From the dialog box that opens, select the file from your device.

3. Open and Install:

In this process, you can only select a file with a .pfx extension.

However, to add certificates with other extensions, you must first add them to Microsoft Windows Store. Once added, repeat the same steps as in the first part and move ahead.

4. Enter Password:

After selecting the file, enter the pass to open the certificate file and hit Enter.

These are the two types of code signing certificate processes you must implement before deploying the solution.

How to Choose the Best Signing Certificate?

Every security certificate has pre-existing security features which determine the level of security they provide to the subject. Be it software, an application, a web app, etc.; the signing certificate has to have the right properties before it’s implemented.

Support for the Latest Hash Algorithm:

Hashing algorithms are sequences or processes that set the security bar in hash value generation. Make sure that the certificate you are getting supports the SHA-2 hashing algorithm. This is the most popular and highly secure function that does not have any anomalies.

32-bit and 64-bit Kernel Mode:

Keeping in mind the advancements in processors and computer technology, always get a certificate that supports 32-bit and 64-bit Kernel mode. This type of certification can work seamlessly with the majority of the devices and platforms.

Supports VS Code:

It is redundant to get a certificate only to see that VS Code is not compatible. So, always take precautions and ensure that your certificate works with Visual Studio Code.

Has Time Stamping for Every Signing:

Time Stamping is an important authenticity aspect in certificate signing. You will receive a valid timestamp certificate from the TSA. Everytime you sign a certificate, the hash of the code is uploaded on the timestamp server.

The purpose is to ensure that your code is working at the time it was signed. So this gives the users another way to check the authenticity.

Eliminates Warning Messages:

Signing Certificates must pass all the requirements set within a system. Failure to do so will result in showing a warning message, which hurts the trust factor. So, you need to get a certificate that passes all the security measures.

Conclusion

Code signing guarantees that the software or program is not corrupted and tampered with. It gives an assurance that the software is safe to use and to download on your system.

It assures that the software is signed by a publisher and that it comes from an authenticated developer or development company.

Microsoft Visual Studio has an in-built code signing system allowing developers to integrate the security certificate after writing the source code and distributing the software with ease.
