Jastegal (Just Another Steganography Algorithm) v.0.1b
|
||
|
|
c0ded by BlackLight <blacklight@autistici.org>
|
||
|
|
|
||
|
|
Usage: ./jastegal [-d|-e] <-i image file> [-o output image file] [-f file to be steganographied]
|
||
|
|
|
||
|
|
-d: Perform a decoding from an image
|
||
|
|
-e: Perform an encoding to an image
|
||
|
|
-i: Specify the input image to be processed. In case of decoding, the content of this file will be de-steganographied,
|
||
|
|
while in case of encoding this is the image to steganography from
|
||
|
|
-o: Specify the output image. This parameter is mandatory in encoding phase, as it specifies the file name containing
|
||
|
|
the image with the steganographied data
|
||
|
|
-f: Specify, in encoding phase, the file containing data to be steganographied. If this option is not specified, the
|
||
|
|
data will be gathered via stdin
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
jastegal -e -i input_image.png -o output_image.png -f file.txt
|
||
|
|
This will encode the data in file.txt using input_image.png as image, and putting the output in output_image.png
|
||
|
|
|
||
|
|
jastegal -d -i input_image.png
|
||
|
|
This will decode the data in input_image.png to stdout
