Steganography Desktop App

❗ Important notes:

• This app's main purpose wasn't originally steganography, rather than just learning more about the process of creating a desktop application. The app is built in a way so that it's hopefully easily expansible, in case I wanted to make changes to it in the future.
• Supports jpg and png files.
• I plan on adding more functionalities to this program, mainly the ability to choose the encryption technique.

Steganography technique

• For this project I chose to simply hide the given message, or data, in the image's hex dump, so there's no pixel/palette processing.

• We only have to append the binary data to the image file.
  • This would be the equialent command in a command line to hide a message:

$ echo "this is a secret message" >> image.jpg
