It’s critical for software developers that users trust the software they’ve developed. Users have the full right to know that the software they’re downloading comes from a trusted source and not any malicious third party. And a code signing certificate helps you achieve that same trust.
Whenever a software publisher has to make its code tamper-proof, it utilizes the Code Signing Certificate. Also, when an organization has to accelerate its trustworthiness, it digitally signs the software using the same certificate.
But have you ever wondered what does Code Signing Certificate mean? And how both individuals and organizations can avail of it. Moreover, most of us need clarification while selecting the Code Signing Certificate.
However, now no more confusion will be there. By reading further, you will get to understand the Code Signing Certificate and all of its types. So, let’s get started.
Interpreting What is Code Signing Certificate
You must have heard software publishers use a digital certificate to secure the source code. It’s none other than the Code Signing Certificate.
It’s a logical security certificate that encrypts the overall code to maintain its integrity and confidentiality.
Moreover, it helps in fulfilling two primary purposes:
- To make the source code tamper-proof
- To fulfill the essential industry and security standards
Likewise, SSL/TLS Certificates, Code Signing Certificates are also issued by the Certificate Authorities. Publishers undergo a validation procedure and submit the required verification documents to obtain such certificates. Moreover, its functionality is not limited to securing only specific software; you can use it to encrypt any executable file.
In addition to its security aspect, publishers also prefer it for eliminating Unknown Publisher Warning. Such warning is an alert message, which system displays when users try to install an application from an unauthorized publisher.
When an end-user faces such a warning, it builds a feeling of doubt in the software and the organization.Therefore, Code Signing Certificates are getting considered to secure the source code and enhance brand legitimacy.
Here’s How Code Signing Works?
Usage of Code Signing Certificate is quite common among publishers and software developers. It helps in providing a unique identity by signing it using digital signature for different applications, macros, plug-ins, executables, and other files before its published.
Likewise, code signing uses PKI technology for authenticating and securing your code, applications, and software.
Below are some common steps involved in working of code signing after your code signing certificate is issued:
- A software developer signs their code, software, or application using a digital signature with the help of a private key provided by a code signing certificate.
- Once a user downloads signed software, the user’s system uses a paired public key to decrypt the signature of that signed software/application.
- For authenticating the signature, the system locates a “root” certificate along with an identity that it recognizes and trusts.
- After locating the root certificate, the user’s system compares the hash used for signing the application towards the hash of the downloaded application.
- Furthermore, if the system recognizes and trusts the root and it matches with the hash, then the download or execution of the software or an application will continue.
- And if the system cannot trust the root or the hash does not match, the system will prevent the download along with the warning message, and the download will fail.
Types of Code Signing Certificates
According to the requirements of different publishers and security levels, there are three types of Code Signing Certificates. Let’s explore them one by one.
Individual (IV) Code Signing Certificate
Individual Validation Code Signing Certificate is particularly for single publishers who work independently. For instance, if you are not working in an organization and want to release your software, then Individual Validation Code Signing Certificate is for you.
It provides the same level of security as a standard Code Signing Certificate. However, the only difference is that the foremost individual publisher can utilize it.
In addition, it assures us to bypass the system warnings, providing a smooth experience to end-users. And the procedure to avail is also seamless. The publisher has to provide a valid government ID to the CA to obtain it.
Therefore, Comodo Individual Code Signing Certificate is a perfect choice if you are a solo software publisher looking to secure executable files.
Standard Code Signing Certificate
As the name suggests, Standard Code Signing Certificate is an organization’s most significant digital certificate. It is also known as Organization Validation Code Signing Certificate. For instance, if an organization has to launch its software, utilizing the Standard certificate is its first alternative.
It helps enterprises to get authenticated by a CA. And it makes them recognized by the operating systems as a legitimate software publisher.
To avail of Comodo OV Code Signing Certificate, the firm has to provide government registration, contact number, physical address, and financial information to the CA. Further, CA cross-verifies it with government records before using the certificate.
Once it gets issued, you can encrypt the source code, perform timestamping and optimize brand value across platforms.
EV Code Signing Certificate
Extended Validation Code Signing Certificate is another digital certificate available for organizations. It gets preferred by IT professionals when a higher security standard is required. EV provides an extreme level of source code protection, as a Hardware Token gets supplied with it.
In Individual and OV Certificates, the overall configuration is in software form. However, for EVs, you get an external USB containing the private key details.
Further, you can store the token behind multiple physical locks and limit access. As a result, only a few people will have access, and unauthorized tampering will get prevented. Moreover, EV Certificates are the only certificates that even bypass Windows Defender SmartScreen Warning.
Hence, you don’t have to worry about any warning, which instantly makes your brand legitimate.
