This repo will contain the algorithms for encryption and decryption of messages and ciphers respectively !!

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

Cryptography Algorithms

These are the lab assignments performed during the course of cryptography

Implementation of various symmetric key encryption systems like AES, DES, triple DES (3 DES), Ceasar cipher, Substitution cipher, Hill cipher

The project aims to improve the serial execution of the DES cryptographic algorithm by implementing it parallelly using OpenMP in C++.

The DES (Data Encryption Standard) algorithm is the most widely used encryption algorithm in the world. For many years, and among many people, "secret code making" and DES have been synonymous

Smart Encryption of data based on best choices using Pandas and PySpark

The project for encrypting files using hybrid cryptography using the AES, DES and RC4 algorithm and then sending the keys using the Diffie Hellman key exchange.

A minimalistic CLI tool to save files in an encrypted format on disk.

Pure python3 implementation of cryptograhic alogrithms
