This is an implementation of all famous cryptography algorithms in python. There are several algorithm of cipher in this like Caesar, Transposition, Substitution, Vigenere, AES and RSA ...

This repository explores classical cryptography, focusing on two major types of ciphers: Substitution and Transposition. The repository provides implementations and explanations for various cipher ...

We all have secrets to keep. Those secrets could be personal dirt we want to keep from others, or they could be something as mundane as our credit card numbers or medical histories. But all of us have ...

This was one of the most secure hand ciphers used in the Second World War. It was used by both the Allies and the Axis, and served both well. Its main weakness was that if the attacker intercepted two ...

However, Agent Madeleine numbered the duplicate A's and L's from right to left instead of from left to right, so it would be the equivalent of replacing the keys with MCHBTUNDILA and CUMLBTJNDIKA, ...

It’s been a couple of Math Mondays since we last looked at columnar transposition ciphers, so let’s jump back in. In the It’s been a couple of Math Mondays since we last looked at columnar ...

Abstract: For increasing attackers and their risks in life, the two parties (sender and receiver) can be using a safe environment to send and receive the secret message by encrypting the message ...

Abstract: The idea behind this paper describes a modality about secret interface over the globalization of the communication over the world. To accomplish this phenomenon, two varieties of security ...
