Usage

The program provides two functions, an encode function that hides the data you want to hide in the specified PNG image and a decode function that retrieves the hidden data from the image.

encode

If you specify the original PNG file and the file you want to hide as parameters, encode.png will be created.

hide-a-leaf encode <cover file> <hide data>

If you want to hide the character string, specify the -text parameter and handle the second parameter as a character string.

hide-a-leaf -text encode {元になるPNGファイル} {隠したい文字列}

decode

If you specify a PNG file that hides the data you do not want to show and perform decoding, decode.png will be created.

hide-a-leaf decode <stego file>

If you want to get it as a string, specify the -text parameter.

hide-a-leaf -text decode <stego file>
