may be useful in some CTF. Feel free to help :)

( This program use Python3 )

## Requirements

This program requires the lib Pillow, which can be installed as follows

```

            pip install Pillow

```

## How to use it

   ### Usage

          python sigBits.py [OPTIONS] [FILE]

   ### Options

   

   Parameters Option | Functionality

   -------------------------------------| --------------------------------------------------------------------

   -h, --help | List all commands and functionality of them

   -t=, --type= | Choose between read LSB or MSB (Default is LSB)

   -o=, --order= | Read the lsb or msb in the specify order (Default is RGB) 

   -out=, --output= | Choose the name of the output file (Default is outputSB)

   -e=, --extract= | Choose between extracting by row or column (Default is Column)

   -b=<8 Bits>, --bits=<8 Bits> | Choose the bits you want to extract info (Have higher priority than '--type or -t')

  ### Examples

  ```

    

    python sigBits.py -t=lsb -o=rgb -out=MyOutputFile -e=row MyInputFile.png

    python sigBits.py -t=LSB -o=BGR -e=column SomeImage.jpg

    python sigBits.py --type=Msb --order=GBR --extract=CoLuMn AnotherImage.png

  ```

  __Note that the input of each options are not case-sensitive, that means you can write with Caps Lock or not__
