# Krypton
- **Krypton** is a JavaScript class with Symmetric (asynchronous and synchronous) and Asymmetric encryption and decryption methods. **Cipher** is configured to use **AES-256-CBC** with initialization vector.
## Usage
### Install
` npm install Krypton-js `
### Require
```javascript
const { Krypton } = require("krypton-js")
```
### Create an instance of Krypton and pass encryptionFileName and Password
```javascript
let Krypton = new Krypton(encryptionFileName, Password)
```
### Encrypt Synchronous
```javascript
Krypton.encrypt(data)
```
### Decrypt Synchronous
```javascript
data = Krypton.decrypt()
```
### Encrypt Asynchronous
```javascript
Krypton.encryptAsync(data).then(result=>{ ... })
// Result = { message: "Encrypted!" }
```
### Decrypt Asynchronous
```javascript
Krypton.decryptAsync(data).then(decryptedData=>{ ... })
//
```
## Asymmetric Encryption/decryption
### A exchanges its public key with B
### A sends data to B, where encryption of data is done with A's Private Key
```javascript
encrypted_data = Krypton.encryptWithRSAPrivateKey( client_request, privateKey )
```
### B: data decryption with A's public Key
```javascript
decrypted_data = Krypton.decryptWithRSAPublicKey(encrypted_data, pubKey)
```
### B to A, encryption with A's public Key
```javascript
encrypted_data = Krypton.encryptWithRSAPublicKey(server_response, pubKey)
```
### A: decryption with A's private Key
```javascript
decrypted_data = Krypton.decryptWithRSAPrivateKey(encrypted_data, privateKey)
```
### Generate a public and private RSA key pair
```javascript
1. ssh-keygen -t rsa
2. openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365
```
