mystipy 0.7.4

A simple Python data obfuscation utility.

mystipy

This is an extremely simple command-line utility for obfuscating and deobfuscating data.

Features

• Data is automatically compressed using gzip.
• Customizable encryption key (XOR) and salt size.
• Prompt mode for interactive input.
• Hexadecimal encoding is used on the output by default, but a --binary override is available.

Installation

The program is a single file, so you can just download/run it manually: python mystipy.py

For the sake of convenience (and to be added to your $PATH), it is also available on PyPI.

pip install --upgrade mystipy

Usage

Basic Commands

• Obfuscate a file:

  mystipy input_file output_file
  

• Deobfuscate a file:

  mystipy input_file output_file --reverse
  

Options

• -p, --prompt: Prompt mode. If provided, you will be prompted for any arguments you don't explicitly set.
• -r, --reverse: Deobfuscate the input file.
• -k, --key: XOR key for encryption/deencryption. Must be a valid byte string. (Default: "mystipy")
• -s, --salt: Number of bytes to use in salt. (Default: 16)
• --binary: Disable exadecimal encoding/decoding. The data will be (or is) compressed binary data.

Examples

• Obfuscate a file with a custom key and default settings:

  mystipy myfile.txt obfuscated.myst -k "hunter2"
  

• Deobfuscate a binary encoded file:

  mystipy obfuscated.myst deobfuscated.txt -r --binary
  

• Use prompt mode for interactive input:

  mystipy -p
  

• Use it in your own program:

  import mystipy
  
  # Define your key and data
  key = "hunter2".encode()
  data = b"I would tell you a joke about UDP, but I'm not sure if you'd get it."
  
  # Obfuscate the data
  obfuscated_data = mystipy.obfuscate(data, key)
  print(f"Obfuscated data: {obfuscated_data}")
  
  # Deobfuscate the data
  deobfuscated_data = mystipy.deobfuscate(obfuscated_data, key)
  print(f"Deobfuscated data: {deobfuscated_data.decode()}")
  

Function Aliases

The script includes function aliases to remove ambiguity if you're using it in your own code:

• mystipy for obfuscate
• demystipy for deobfuscate

import mystipy
print(mystipy.mystipy == mystipy.obfuscate)       # True
print(mystipy.demystipy == mystipy.deobfuscate)   # True

So if you'd prefer to use the aliases, you'd import the obfuscation/deobfuscation functions like this:

from mystipy import mystipy, demystipy
