Steg

Command line steganography tool.

Notice

I am trying an experiement - i am trying to restructure the way steg works.

Currently i am re-implementing the 3 working strategies another way that should scale more nicely meaning that more strategies will be easier to add later on.

Feel free to add strategies in the current way and i will still merge them. :rocket:

Terms

• payload - the secret message or content to be hidden

• carrier - the entity in which you are trying to hide a payload

• package - the result of hiding the payload in the carrier

• encoding density - the normalised proportion of the package that the paylaod has affected

• channel - describes the type of carrier in which the payload will be hidden

• scheme - the way in which a payload will be hidden in the specific type of channel

• stratagy - refers to the combination of a channel and a scheme

Usage

cargo install steg (you must have [cargo](https://crates.io/install) installed)

// Hide something
steg hide -p ./payload.png -c ./carrier.png -o ./output.png

// Reveal something that was hidden
steg reveal -c ./output.png

The below is a plan of the supported payload and carrier types and default strategies for use with each.
