BaseCrack is a tool written in Python that can decode all alphanumeric base encoding schemes.

Overview

BaseCrack

Decoder For Base Encoding Schemes

version GitHub license

BaseCrack is a tool written in Python that can decode all alphanumeric base encoding schemes. This tool can accept single user input, multiple inputs from a file, input from argument, multi-encoded bases, bases in image EXIF data, bases on images with OCR and decode them incredibly fast.

For a basic demo, try the Web Interface that uses BaseCrack's API.

Fun Fact!
I initially made this after being fed up with lame CTF challenges with multi-encoded bases. Now some of them started doing that in Steganography challenges so I automated that too smh!

Table of Contents

Features

  • Decode multi-encoded bases of any pattern.
  • Decode bases in image EXIF data.
  • Decode bases on images with OCR detection.
  • Can decode multiple base encodings from a file.
  • Generate a wordlist/output with the decoded bases.
  • Predicts the type of encoding scheme.

Supported Encoding Schemes

  • Base16
  • Base32
  • Base36
  • Base58
  • Base62
  • Base64
  • Base64Url
  • Base85
  • Ascii85
  • Base91
  • Base92
  • Base100 (#14)

Installation

$ git clone https://github.com/mufeedvh/basecrack.git
$ cd basecrack
$ pip3 install -r requirements.txt
$ python3 basecrack.py -h

NOTE: Python3 is recommended to use!

Linux:

$ sudo apt-get update
$ sudo apt-get install tesseract-ocr libtesseract-dev

MacOS:

$ brew install tesseract

Windows:

OCR Detection is implemented with Tesseract and Windows requires installation of the Tesseract executable. Installing the dependencies from requirements.txt which includes pytesseract should install it. If in case it doesn't, here's how you can set it up:

  1. First check whether you have it installed or not in the Program Files/Program Files (x86) under the Tesseract-OCR directory.
  2. If there is, give that path in the config.json and you're all set! If you don't have it, install it from here and set the path in config.json.

Tesseract Docs: https://tesseract-ocr.github.io/

NOTE: I haven't completely tested this tool on Windows so if you stumble upon any issues, please open an issue.

Usage

Get a list of all the arguments:

python3 basecrack.py -h

To decode a single base encoding from user input:

python3 basecrack.py

To decode a single base encoding from argument (-b/--base):

python3 basecrack.py -b SGVsbG8gV29ybGQh

To decode multiple base encodings from a file (-f/--file):

python3 basecrack.py -f file.txt

Magic Mode: To decode multi-encoded base of any pattern (-m/--magic):

python3 basecrack.py --magic

To input an image for EXIF/OCR detection mode (-i/--image):

python3 basecrack.py -i image.jpg (--exif/--ocr)

EXIF Data: To decode bases in image EXIF data (-e/--exif):

python basecrack.py -i image.jpg --exif

OCR Base Detection: To decode bases on image with OCR detection (-c/--ocr):

python basecrack.py -i image.jpg --ocr

To generate a wordlist/output with the decoded bases (-o/--output):

python basecrack.py -f file.txt -o output-wordlist.txt

Magic Mode

Now you can decode multi-encoded bases of any pattern in a single shot.

Have you ever stumbled upon that one lame CTF challenge that gives you an encoded string which is just encoded over and over with Base64, Base91, Base85 and so on? Just give that to BaseCrack and you're done with it! ;)

Want to test it out? Just give it this input:

IX([email protected]<,*TFE]IT^zdINAb9EVbp,e
   
    <*[Nv+T8

   

and see for yourself! :)

BaseCrack API

BaseCrack can now be used as a library! Just import the BaseCrack() class and call the decode() function.

See API.

API

Want to use BaseCrack as a library? We got you covered!

Just put basecrack in your project's directory and you're ready to go!

Example:

# import the BaseCrack class from basecrack.py
from basecrack import BaseCrack

# calling the api function decode() with the encoded base
result = BaseCrack().decode('c3BhZ2hldHRp')

# printing the output
"""
result is tuple where:
result[0] = DECODED STRING
result[1] = ENCODING SCHEME
"""
print('Decoded String: {}'.format(result[0]))
print('Encoding Scheme: {}'.format(result[1]))

Output:

Decoded String: spaghetti
Encoding Scheme: Base64

  • base62 decoding not working

    base62 decoding not working

    Hi,

    I think there is a bug in the base62 decoding attempt.

    Should not the line

    base62_decode = base62.encode(int(encoded_base)).decode('utf-8', 'replace')

    read something like

    base62_decode = str(base62.decode(encoded_base))

    ?

    For instance, with base-62 from pypi I get

    In [3]: base62.encode(999)
    Out[3]: 'g7'
    

    With the original basecrack.py:

    $ python3 basecrack.py -b 'g7
    [-] Encoded Base: g7
    
    [>] Decoding as Base91: 
    
    [>] Decoding as Base92: Â
    
    

    With my suggested modification:

    $ python3 basecrack.py -b 'g7
    [-] Encoded Base: g7
    
    [>] Decoding as Base62: 999
    
    [>] Decoding as Base91: 
    
    [>] Decoding as Base92: Â
    
    [-] The Encoding Scheme Is Base62
    

    Moreover, I find disagreeing results when I encode a integer with base-62 and with pybase62 (both taken from pypi).

  • Not detecting base32 encoded string

    Not detecting base32 encoded string

    I pulled the following string from a CTF:

    wvcpRLNKBz2zqpFs9UcrvLAgXjgwyquv4GbW2FXC9Y7ZW4dzkcZk9t7t3vSnjdUDUwBCVDZdj6XZ5xoTr6UXxbag1PrytSVoU5ZzCinrYsMJ7Aac8A8S7cJTmnbSs9PZHgEmRCkMir2WWYygs7SwESfbTV

    decoding from base32 and then running the magic flag on it works, but doesn't with the first base32 later. base32 -d doesn't work with it either, but cyberchef does. I assume its because of some issue with the specifics of identifying a base32 string, but not sure.

    hi,I encountered "!" when decoding base85

    If there is a "!" in the "shell" you will get this error image And to avoid this mistake is to give "!" with "", but then it will not be decoded properly image

    Fix base62 error and add Ascii85

    This fixes https://github.com/mufeedvh/basecrack/issues/4#issue-700623958 by replacing base-62 with pybase62. Uninstalling the old dependency before installing the new dependency is required.

    It also adds support for Ascii85 encoding.
