How To Validate Digital Signature In Google Chrome

by

A digital signature acts as a way to verify the authenticity of digital documents, ensuring their integrity and the identity of the sender or signer. This blog post provides a step-by-step guide on how to validate a digital signature in Google Chrome.

What is a Digital Signature?

A digital signature is a cryptographic technology that is used to confirm the authenticity of digital documents or software. In simpler terms, it’s a bit like having a personal, digital ID card. By attaching a digital signature to your digital content, you’re able to provide evidence of your identity and ensure that the content hasn’t been tampered with.

How Does it Work in Google Chrome?

Google Chrome automatically checks the validity of digital signatures on downloaded files and updates. However, it does not provide an explicit option to verify digital signatures directly. To manually check the digital signature of a downloaded file, you will need to use the built-in features of your operating system.

Checking a Digital Signature on Windows

Here’s how to verify a digital signature for a file on a Windows PC:

  1. Right-click on the downloaded file.
  2. Select ‘Properties’ from the context menu.
  3. Switch to the ‘Digital Signatures’ tab.
  4. In the ‘Signature list’, select a signature and click on ‘Details’.
  5. If the message ‘The digital signature is OK’ appears, the validation has been successful.

Checking a Digital Signature on Mac

For Mac users, here’s how to validate a digital signature:

  1. Open Terminal.
  2. Use the codesign command and the path to the file you want to check. Your command should look like this: codesign -dvvv /path/to/yourfile
  3. If the file is correctly signed, you will see the signature information in the output.

Conclusion

Verifying digital signatures is essential to maintaining the security of your digital content. This process confirms the authenticity of the sender and ensures that the content hasn’t been tampered with. Although Google Chrome doesn’t provide a direct way to validate digital signatures, using the inbuilt features in your operating system makes the process simple and straightforward.
