PNG Chunk Message Encoder/Decoder in Rust

This project is an implementation of a PNG message encoding/decoding tool using Rust, inspired by the PNGme Book. It provides a command-line interface (CLI) and a graphical user interface (GUI) built using the Iced framework.

Folders:

• cli: Contains the command-line interface implementation, including assets like 382px-PNG_Test.png and the main encoding/decoding logic.
• core: Houses the core logic of the PNG encoding/decoding process, which can be used by both the CLI and GUI.
• gui: Contains the GUI application built with the Iced framework for a more user-friendly interface.

Features

Command-Line Interface (CLI)

The CLI provides four main commands for interacting with PNG images and secret messages:

1. Encode a message:

   png-chunk-msg-cli encode ./dice.png ruSt "This is a secret message!"
   

2. Decode a message:

   png-chunk-msg-cli decode ./dice.png ruSt
   

3. Remove a chunk:

   png-chunk-msg-cli remove ./dice.png ruSt
   

4. Print chunk information:

   png-chunk-msg-cli print ./dice.png
   

Graphical User Interface (GUI)

The GUI offers a more intuitive way to interact with the PNG message encoding/decoding system. It is powered by the Iced framework, providing a cross-platform application to encode, decode, and manage chunks in PNG files.

Requirements

• Rust (latest stable version)
• Cargo (Rust package manager)
• Iced (for the GUI)
• [Clap,Rfd] (for the CLI)

Installation

For the CLI:

cargo run -p png-chunk-msg-cli help

For the GUI:

cargo run -p pcm-gui
