What is Code Signing?

Code signing is a process of digitally signing the code of your software, application, or executables. It ensures the users of the software that its code has not been tampered with and is safe to use.

A code signing certificate verifies the identity of the publisher using a hash function and certifies that no modifications have been done to the software since it was published.

All modern OS when installing new software or application, validate digital signatures to ensure software integrity. In case the digital certificate is not present, it warns the user that the software may be unsafe to use.

Code Signing Process

There are several steps included in the code signing process. The process starts with the creation of a unique key pair. As the code signing process leverages  public key cryptography, a unique pair of public-private keys is created.

After its creation, the key is sent to the certification authority (CA) from where you are buying your certificate.

The CA returns the public key to the software developer verifying that the key belongs to the software publisher. It then issues a code signing certificate to the owner. After your return of digital code signing certificate and public key, the code is run through a hash function.

The hash function transforms the software code into an arbitrary mixture of values which is encrypted using the private key. Now this encrypted code, hash function, and code signing certificate are combined together into a signature block and added to the software.

After receival of the software, the user computer firstly verifies the authenticity of the code signing certificate. Once confirmed, the encrypted data is decrypted with the original public key. Lastly, the has function in the system is matched with sent software, which determines the software is safe to install in your system.

What are the Benefits of Code Signing?
