LSBSteg

• A simple steganography tool using the least significant bit of every byte in *.bmp files to store hidden data.
• Mainly referenced from Omiher's work.

Usage

• Python 3.x with Tkinter installed
• PIL package (Mention: In Mac, install it by 'sudo pip3 install pillow'.)
• run 'python3 GUI.py'

Instruction

• This steganography tool is compitable with both 256 gray & 24 bit true color bmp files.
• Apart from the first 1078 bits in header, I use the next 32 bytes to store the length of hidden message.(An int is 32 bits long, which can be hidden in 32 bytes.)
• So a 256 gray bmp file with 'wh-32<=0' or a 24 bit true color bmp file with 'wh*3-32<=0' can not hide message using this tool.
