Implementing Auto Encryption and Decryption in VSCode: A Step-by-Step Guide

Visual Studio Code (VSCode) is a powerful code editor widely used by developers, but you may encounter situations where you need to manage encrypted files. For instance, you might have a file that is encrypted in a simple manner—where every character is shifted by one bit—and you want to be able to edit it. The challenge is to have VSCode automatically decrypt the file when opening it, and encrypt it again when saving.

In this guide, we will walk you through how to implement this functionality using VSCode’s extension API.

Understanding the Problem

When you work with encrypted files, editing can become cumbersome if you don't have a straightforward way to view and edit the file's content. In this case, our goal is to automate the following processes:

Decrypt the file on opening: This allows for human-readable text editing.

Encrypt the file on saving: This ensures the integrity and security of the data.

You might have already achieved this using a Notepad+ + plugin, but in this guide, we will translate that functionality to VSCode.

Setting Up Your VSCode Extension

To implement this functionality in VSCode, we will use specific VSCode events:

onDidOpenTextDocument: This event triggers when a document is opened.

onDidChangeActiveTextEditor: This event triggers when the active text editor changes.

onDidSaveTextDocument: This event triggers when a document is saved.

Step 1: Installation and Activation

If you haven't already, you need to create a basic VSCode extension. You can do this using the Yeoman generator for VSCode extensions. Once you have your environment ready, we can dive into the code.

Add the following code to your extension, typically in the activate function:

Step 2: Decrypt Function

You need a simple decryption function to transform the shifted characters back to their original form. This could look something like the following:

Step 3: Encrypt Function

Similarly, for encryption, you can create a function like this:

Step 4: Testing Your Extension

After implementing the functions, your extension should be ready for testing. Open a .txt file containing encrypted data, and check if it gets decrypted correctly when opened, edited, and then re-encrypted upon saving.

Conclusion

Automating the encryption and decryption of files in VSCode streamlines the editing process for developers dealing with encrypted content. By following the steps outlined, you can implement a smooth and efficient workflow for working with sensitive files. Remember that keeping your code organized and structured is key for maintainability.
