Examples

steganopy exampleimage.png e -t "test text" -v r

- Will only utilize the red values in the image to put the information in.

steganopy exampleimage.png e -t "test text" -o "newname"

- Will output the file with the name "newname" instead of the default name of the original filename with -steganopy appended to it.

steganopy exampleimage.png e -f exampletext.txt

- Will get text from the exampletext.txt file to use.

steganopy exampleimage.png e -e trinary

- Will encode the information in base 3 (trinary) instead of the default of binary.

steganopy exampleimage-steganopy.png d -v r

- When decrypting, the values used in encryption must be the same, otherwise errors may be thrown.

steganopy exampleimage-steganopy.png d -v r -o test

- When decrypting, you can also use the -o --output argument to have the information be outputed into the a text document with the specified name.
