👨‍💻 Computer Security algorithms in C#

Cryptography and Network Security Lab programs done in 7th semester of SIT(VTU).

crypto fun repository

Implementation of Ciphers

Monoalphabetic Cipher in python

Cryptographic application in C#

Program that encrypts plaintext and (attempts) to decrypt ciphertexts, encrypted via a mono-alphabetic substitution cipher. Replaces letters based on frequency / n-gram analysis. Tried to incorporate hill-climbing algorithm by measuring the fitness of resulting texts to find the best key.

Implementation of various cipher algorithms

GTU Information and Network Security ( INS ) in python .

Monoalphabetic crypting/decrypting script written in plain Javascript.

Solves substitution cipher algorithm on short text without spaces

In this program, we want to create an unlimited chatroom based on TCP/IP between the client and the server.

This project contains implementation of some cryptography algorithms using C# language.

Assembly code for 8086 machine to encrypt/decrypt alphabets

Introduction to basic Cryptography through a game

The Monosar Project is used to implement Caesar Cipher and Mono-Alphabetic substitution

A program which performs a frequency analysis on a sample of English text and attempts a cipher-attack on polyalphabetic substitution ciphers using 2 famous methods - Kasiski's and Friedman's.
