Hill Cipher

https://en.wikipedia.org/wiki/Hill_cipher

Character mapping Matrix

A-->1 ... Z-->26

a-->27 ... b-->28

and so on..!! see code

Platform

LINUX build only

GUI is coming in future possibly

First clone the repo

then go to the project directory and build and run so simple

 Sample matrix is given in input.txt

Build

make

Run

make run

Clean

make clean

Programm Output Representation

Core Logic of the Program

Hill Class

namespace is used as helped class

OOP

All namespace methods are completely reuseable

Good side

No memory leak, uninitized value as programm is checked by google sanitizer

Downside

seperation of concern

Only decryption will not work well here because encrypted code is rounding using required  modulo

To work with decrypted code you have to work with value not with character

Linux Terminal Issue

Linux termios object is called in linuxUtil.hpp file

If Program crash unexpectedly badly, then you have to close the terminal

This codebase is POSIX compatible

Improvement

You can apply c++ template(generic) easily
