Stegano CLI

Implements LSB steganography for PNG image files in rust-lang.

Aims for compatibility to the Stegano for windows version

Watch it in action

Quick Start

Install

To install the stegano cli, you just need to run

cargo install --force stegano-cli

(--force just makes it update to the latest stegano-cli if it's already installed)

Note the binary is called stegano (without -cli)

to verify if the installation went thru, you can run which stegano that should output similar to

$HOME/.cargo/bin/stegano

Hide data

Let's assume we want to hide data of a file called README.md, into an image called HelloWorld.png, based on a image called resources/with_attachment/Blah.txt.png. So we would run:

stegano hide \
 --data README.md \
 --in resources/Base.png \
 --out README.png

or by cargo

cargo run -- hide \
 --data README.md \
 --in resources/Base.png \
 --out README.png

The final result is then contained in the image README.png.

Unveil data

Let's unveil the README.md that we've hidden just above in README.png

stegano unveil \
 --in README.png \
 --out README-2.md

or by cargo

cargo run -- unveil \
 --in README.png \
 --out README-2.md

Unveil Raw data

Let's unveil the raw data of the README.md that we've hidden just above in README.png

stegano unveil-raw \
 --in README.png \
 --out README.bin

The file README.bin contains all raw data unfiltered decoded by the LSB decoding algorithm. That is for the curious people, and not so much interesting.
