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. 🚀
