CryptoClassification Kit

Introduction

This is an effective kit for Crypto-text Classification which is created to classify the different ciphertexts encrypt by different encryption algorithms. In short, it handles the Classification task.

Though it can only distinguish 4 different encryption algorithms, it has completely open up a new window to Cryptanalysis. By using this kit you can train a high-performance model or you just use the model that we had already provided.

How to use it

  1. run main in backend.py, see the routine and you will find how it works.
  2. Make Sure there is any trained model in the folder trained_model if you run method getCipherResult.(This means you want to use the model we provided.)
  3. Make Sure there is a folder named self_model if you run method getTrainedModel and then you need provide data in ./static/CiphertextFile/ .

The format of data to offer is: which ciphertext file for which encryption algorithms is in which folder.
e.g. If you have 2 kinds of ciphertexts, one is encrypted by AES and other is by 3DES, then put these ciphertexts into corresponding folder named ./static/CiphertextFile/AES/ ./static/CiphertextFile/3DES. (This means you want to train a model by yourself so you should load data.)

  1. For 2 and 3 you can unzip the compressed files self_model.zip, trained_model.zip.
  2. You really can understand the meanings simply through its name.
