pngchat

Hide messages in the PNG file.

The intent of this little project is to learn how to encode PNG file and add some messages inside it

Idea come from PNGme: An Intermediate Rust Project

Goal

Making a command line program that lets you hide secret messages in PNG files.

The main tasks of pngchat are:

• Encode a message into a PNG file
• Decode a message stored in a PNG file
• Remove a message from a PNG file
• Print a list of PNG chunks that can be searched for messages

Uasge

```bash

Encodes a message into a PNG file and saves the result

pngchat encode ./test.png ruSt "This is a hidden message"

Searches for a message hidden in a PNG file and prints the message if one is found

pngchat decode ./test.png ruSt

Removes a chunk from a PNG file and saves the result

pngchat remove ./test.png ruSt

Prints all of the chunks in a PNG file

pngchat print ./test.png ```
