In the era of cyber threats, product vendors and users must have the best security measures, especially when downloading software and products online. One such security measure is Code signing. 

Code signing is the digital signature most software vendors add to their applications and software to help the user verify that the codes are not tampered with after signing the code. It is also used to help the user verify the valid software owner and manufacturer. 

Code signing includes a signature, timestamps, company names, and other details the company may desire. These details are not only there for verification purposes; there are other benefits as well.

So, before using Code signing, you should be aware of its various benefits and facts. 

How does it work?


The code signing process is similar to other digital product safety and security features such as those used for SSL certificates which rely on cryptographic keys, private and public, to authenticate the products. In code signing, you need to generate private keys and use them for security measures.

One of the ways to obtain the private key is to apply from trusted sources such as certificate authorities (CA) to guide you through the authentication and verification process.

Once you get the certificate, you can generate your private key. You then use the private key to sign into a library of software. The private key is tracked using the public key traced by the CA installed in your browser to access the software. If someone tampers with the code, you will be unable to download the software since the browser will flash a safety warning whenever anyone tries to download the software. If the code is untampered with, you can safely download the software. 

Steps in code signing


The code signing process involves various steps that you must observe. Missing a step interferes with the whole process. The first step is the creation of public and private keys using public key cryptography. The second step is submitting the key to the CA for verification. The CA will then return the public key to the software developer alongside the code signing certificate. This process is critical to protect intellectual property and verify the trustworthiness of the software.

The third step is running the software through the hash function. This process is to ensure software security since it involves the encryption process. The hash function turns the texts into a mixture of irreversible values, which are then compared with the software data before the software is submitted to the consumer.

The consumer then uses the private key to decrypt the texts. This process ensures nobody tampers with the software because only one person can have the private key. Once decrypted, you can begin the installation process. 

Application areas of code signing?


The greatest beneficiary of code signing includes the following:

  • Product users: They can easily verify authentic applications from fake products. The code will only allow them to download genuine, certified, legit products. 
  • Enterprise IT: the IT team needs code signing as a security feature for the product developed. They need it to ensure the internal scripts and utilities are code signed, preventing tampering from internal users and other company threats. 
  • IoT manufacturers: It secures IoT devices using firmware and software obtained legitimately, preventing security threats.
  • Mobile App developers: App distributors must meet standards by Google App store and Apple which require all applications code to be signed before being uploaded to the sites. 
  • Software vendors: Software needs code signing to support the installation process. If the software is not code-signed, OS like Windows and Mac Os will always warn about the dire threats. 

Weaknesses of code signing 


Despite being more effective than other authentication procedures, code signing can have specific weaknesses. There is potential for improper management that can lead to insecurity. If a hacker steals a private key, they can easily encode their malicious software using the key. 

Secondly, users can decide whether to ignore the security warnings and perform the installation. The code signing becomes useless on such occasions because it is not ideal for the verification process. The vendor has no control over the user’s actions.

How to code signing protect intellectual property?


The vendor or manufacturers can easily track file modifications when a code is digitally signed. The time stamps enable the author to confirm whether the code was signed using a valid certificate even after the expiry of the certificate. The users can also use the digital information to track the application expiry date and implement the renewal process. 

Why is it necessary?

It protects the software from distributors by allowing only trusted service providers for the code signing of any software and mobile applications. Secondly, it is necessary for software and application developers to prove the legitimacy of their products uploaded on platforms such as Google and Apple. 

The process helps the company boost its customer relationship by providing only genuine products verified by the code signing process. This enables the customers to trust the products since they are not fake. It allows software developers to fully benefit from their products by curbing piracy, copying, and protecting their intellectual property. 


Before you purchase and install any software, you must ensure they are code signed to avoid dealing with challenges such as security warnings or exposing your system to attacks. Code signing will help you get the product from a natural source and install it without complications. Code signing can also benefit companies by boosting revenue from products and reputation and preventing copying or selling similar and fake products.
