Cryptography Project

This project implements several classical ciphers in Python. The ciphers included are:

• Caesar Cipher
• Hill Cipher
• Playfair Cipher
• Rail Fence Cipher
• Vigenère Cipher

Caesar Cipher

The Caesar Cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet.

Hill Cipher

The Hill Cipher is a polygraphic substitution cipher that encrypts blocks of plaintext into ciphertext using matrix multiplication.

Playfair Cipher

The Playfair Cipher is a digraph substitution cipher that encrypts pairs of letters in the plaintext into pairs of letters in the ciphertext.

Rail Fence Cipher

The Rail Fence Cipher is a transposition cipher that rearranges the letters of the plaintext by writing them in a zigzag pattern.

Vigenère Cipher

The Vigenère Cipher is a polyalphabetic substitution cipher that encrypts the plaintext by shifting each letter according to a keyword.

Usage

To use the ciphers, simply import the corresponding module and run the main.cpp file using your favourite c++ compiler
