A steganographic binary generation tool
The goal of stegosaurus is to be able to hide data in various binary forms:
- images,
- sound files,
- etc.
Should work with all image types, though only tested with bmp/jpg/png.
NOTE: When embedding with a non-bitmap cover, you should specify the output with a bitmap-type extension (i.e. png or bmp). Due to lossy compression with jpg files, your data will be unrecoverable since this tool only does LSB at the moment.
Besides the rust toolchain, which is only necessary for building, you will need the following installed on your system:
- openssl
Here is an example of embedding plain text in a png file. Note that the message will be encrypted before being embedded.
$ echo "super secret message" | ./stegosaurus embed --cover ~/png-files-download-6.png --output innocuous.png
passphrase:
confirm:
$ ./stegosaurus extract --cover innocuous.png --output message.txt
$ cat message.txt
super secret message
- Support for sound files (.wav files only)
- Add more steganographic methods (e.g. customizing how many LSBs).
- Probably more to come
Build using cargo build, and run tests with cargo test
