Implements LSB steganography for PNG image files in rust-lang.
Aims for compatibility to the Stegano for windows version
To install the stegano cli, you just need to run
bash
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
bash
$HOME/.cargo/bin/stegano
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:
sh
stegano hide \
--data README.md \
--in resources/Base.png \
--out README.png
or by cargo
sh
cargo run -- hide \
--data README.md \
--in resources/Base.png \
--out README.png
The final result is then contained in the image README.png.
Let's unveil the README.md that we've hidden just above in README.png
sh
stegano unveil \
--in README.png \
--out README-2.md
or by cargo
sh
cargo run -- unveil \
--in README.png \
--out README-2.md
Let's unveil the raw data of the README.md that we've hidden just above in README.png
sh
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.
