crypttool

This is my little commandline tool which I wrote to learn Python. It performs various cryptographic and miscalleneous tasks.

Instructions

1. Clone this repository.
2. cd crypttool
3. chmod +x crypttool.py
4. ./crypttool.py

Features:

ROT/Ceasar "Encryption"

• Allows rotating strings by a given amount, aswell as 'bruteforcing an encrypted string (when asked, type all)

Hashing

• Can hash files (absolute paths) or strings
• Supports all algorithms from hashlib

Translation

• Translate/convert strings between binary, decimal, octal, hex and ASCII

Base64 Encoder/Decoder

• Guaranteed to work with strings and files (this is not a guarantee)
• Uses a regex to automatically detect b64 strings
• Needs absolute Paths for files
• currently broken (atleast for files)

String Reverser

• .syas ti tahw seod

Fixed XOR

• XORs two hex strings

Single Byte XOR Bruteforce

• Takes a file or a string
• Tries to XOR decrypt with a key between 0 and 255, then returns the best matching results

XOR Repeating Key

• I'm not sure anymore but I think this doesn't work

Zero-Width Strings

• Create binary-encoded zerowidth-strings to hide in your texts
• Or find and decode them!
