ReSteganographer

README

ReSteganographer

A minimalist command-line tool for hiding and extracting secret messages within PNG images using Least Significant Bit (LSB) steganography. It embeds data into the RGB channels while preserving the alpha channel to maintain image transparency. A 4-byte length header is automatically prepended to the payload to facilitate decoding.

Installation

go install github.com/ree-verse/ReSteganographer@latest

Usage

Encode a secret message:

resteganographer encode -i input.png -o output.png -m "Your secret message"

Decode a hidden message:

resteganographer decode -i output.png

Example

Original	Encoded
-	Hidden message: Hey, this tool works (really) well, right?

Code note

Certain functions and variables are intentionally only used once, for readability purposes.
