Cryptography

General Information

Here you will find encryption and decryption codes using AES256, RSA. Hash operations using SHA256, Object-Hash etc. Digital signature and encryption, decryption together using RSA. End-to-end encryption using Elliptic-Curve Diffie-Hellman, Diffie-Hellman algorithm etc.

Setting up

You must follow the steps below to setup the environment and use the codes:</br>

Step 1: Download or Clone this repo by: </br> git clone https://github.com/mdmuhtasimfuadfahim/Cryptography </br>

Step 2: From the root directory, run this command to install dependencies:</br> yarn install or npm install </br> It will install all the dependencies in your device.</br>

Step 3: Change directory and run each files in each folders following the commands:</br> example: cd AES256</br> node aes-256-ctr</br> </br>You will be able to see the results in console and you may change the console by your own need.</br>
