zwsp-steg-py

Zero-Width Space Steganography. Encodes and decodes hidden messages as non printable/readable characters. This repository is a Python porting of zwsp-steg-js. All credits to offdev!

Installation

$ pip install zwsp-steg-py

Usage Example

import zwsp_steg

encoded = zwsp_steg.encode('hidden message')
decoded = zwsp_steg.decode(encoded)

print(decoded)  # hidden message

Note that decoding a message will ignore all non 'special' characters. That means if you hide your message within a readable string, and decode the whole string, you will only return the hidden message.

Parameters

You can use different sets of characters in different encoding / decoding modes.

import zwsp_steg

zwsp_steg.encode('hidden message', zwsp_steg.MODE_ZWSP)
zwsp_steg.encode('hidden message', zwsp_steg.MODE_FULL)

Character sets used

• MODE_ZWSP: Zero-Width Space (\u200b), Zero-Width Non-Joiner (\u200c), Zero-Width Joiner (\u200d)
• MODE_FULL: All MODE_ZWSP characters, Left-To-Right Mark (\u200e), Right-To-Left Mark (\u200f)
