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.

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!

Features

Supported Encoding Schemes

Installation

$ git clone
$ 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:

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 SG

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 e 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:

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.
