Is it possible to protect assets aside from JavaScript in Nodewebkit?

After coming across a post about securing the source code in a node-webkit desktop application on Stack Overflow, I began contemplating ways to safeguard my font files. Would using a snapshot approach, similar to the one mentioned in the post, be a viable option for this purpose?

Instead of utilizing the command:

nwsnapshot --extra-code application.js application.bin

I wondered if running:

nwsnapshot --extra-code font_file font_file.bin

and then including the following in package.json would achieve the desired security:

snapshot: 'font_file.bin'

Alternatively, is there another method to reference the binary font file? Is it feasible to convert the CSS file that references the font into binary format? Moreover, can languages other than JavaScript be converted into binary as well?

Answer №1

If you're looking to enhance the security of your files, one option is to encrypt them and then add them dynamically through JavaScript by decrypting them. Node.js offers methods for encryption and decryption that can be utilized for this purpose.

Additionally, it's possible to merge your assets with the executable file, although this method may not provide foolproof security as the resulting file can still be opened like a zip archive. This process involves creating a zip of your content (including package.json), renaming it to "package.nw", and then merging it into the exe file using a command like: 

`copy /b nw.exe+app.nw app.exe `
For detailed instructions on how to perform this in various operating systems, refer to: https://github.com/nwjs/nw.js/wiki/How-to-package-and-distribute-your-apps#step-2a-put-your-app-with-nw-executable

It's important to note that while these measures can increase security to some extent, the packages.json file remains a vulnerable point in the application without any specific protection from NW.js.

Stay secure!
