What is a code signing certificate?

 

Software developers digitally sign their software programs via code signing certificates. This helps the system to verify that the code received is from a reliable source. The code’s signature also includes details like your name, your company’s name, and the timestamp if desired.

And this adds an extra layer of user confidence and trust.

Below is an example of what software without a code signing certificate looks like.

Now compare both these prompts. Especially the ‘Publisher’ Name. The software with the code signing certificate clearly states that its publisher is verified. Whereas the one without, states its publisher as ‘Unknown’.

You must’ve uninstalled certain software once you found them to be from an unreliable source.

Therefore, just like you, other users drive themselves away from unreliable software too. Whereas users tend to stick with software that belongs to a reliable publisher i.e., software that consists of a code-signing certificate.

Meanwhile, users also recommend your software to others thus increasing the downloads of your software.

Investing in security measures for your IP ALWAYS pays for itself.

 

How do code signing certificates work?

 

Now that you know what code signing certificates are… let’s now throw some light on how they work.

 

The Verification Process of a Code Signing Certificate:

  1. You sign your software using a code signing certificate.
  2. A digital signature (Verification mark) is attached to your software and a hash mark is created.
  3. When a user downloads the file, the user’s system uses a public key to decrypt your software’s signature.
  4. The hash on the user’s downloaded file is compared with your software’s hash.
  5. When all the strings of data match, the identity is verified.

All this goes on internally. If the codes, hashes, signatures, etc. do not match, you and the user will be notified.
