# Stegosaurus
[](https://www.github.com:Towerism/stegosaurus)
> 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.
## Requirements
Besides the rust toolchain, which is only necessary for building, you will need
the following installed on your system:
- openssl
## Example usage
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
```
## Roadmap
- Support for sound files (.wav files only)
- Add more steganographic methods (e.g. customizing how many LSBs).
- Probably more to come
## Development
Build using `cargo build`, and run tests with `cargo test`
