One Time Pad and Perfect Secrecy

Introduction

The project is one of the experiments of the virtual lab (cryptography lab) of IIITH Standard template of the frontend is used and the backend is made using python.

Running the Experiment

Step1 --> Run the Experiment.py file using command :-

					$ python3 run.py

Step2 --> Open the browser and open the following link

						"localhost:5000/"

Testings

Step1 --> Run the Experiment. (Testing is to be done on a new terminal)

Testing is done in two steps:-

1. Test for all the links to pages Run the Links_Test.py file using command

			 $ python3 links_test.py		

2. Unit testing for logic part of the Experiment Run the Unit_tests.py file using command

			$ python3 tests_app.py				

Installing and Prerequisites

sudo apt-get update
sudo apt-get install python3.6
sudo apt install python3-pip
pip3 install Flask
sudo apt-get install sqlite3
pip3 install sqlalchemy
pip3 install -U Flask-SQLAlchemy
pip3 install Markups
pip3 install requests

Built With

• Python Flask
• javascript Ajax

About the code

The templates directory:-

This contains all the html pages which form frontend of the experiment. It also containts the javascript and ajax code to generate requests to the app experiment.html page has the experiment page which basically is composed of three forms and the quiz.html page has five questions which are retrieved at the frontend by ajax request to the app.py file Rest all have only plain html which is used to display the content of the respective pages Also the code in index.html is imported to all the html pages

The static directory:-

This directory contains all the required css javascript files used to make the frontend of the website

The controllers.py file

It consists of three databases The first one is for storing the key and plaintext pairs which user enter The second one is for the storing of the 2^8 plaintext for generating the encryption set The third one is for storing the quiz questions

The models.py file

The models.py is the file which contains all the backend of the experiment

It consits of four forms for handling the various buttons on the html page and also one check function which is used to evaluate the answers of the quiz and give you a score

form1 contains 3 buttons form2 contains 1 button form3 contains 1 button form4 contains 2 buttons

All of these have a seperate redirection function so as to generate different request for each button Also there are custom functions in this file and to make viewing what is stored in the database easier All the fuctions and variables have intutive names so that debugging is easier

The test_app.py

This file contains the unit test cases for form elements This file contains the unit test cases for links

The createTextDatabase.py

This file can be run when one wants to generate the 2^8 plaintext database

The createquizbasequiz.py

This file can be run when one wants to generate the quiz database
