Vvlad1973-crypto NPM

vvlad1973-crypto

A simple TypeScript class for encrypting and decrypting text using specified cryptographic parameters (algorithm, password, etc.).

This class is a wrapper for the aes-js library.

Installation

You can install the package via npm:

npm install vvlad1973-crypto

Usage

Here are some examples of how to use the Crypto class in your project.

Importing the Crypto Class

In a CommonJS module environment (Node.js):

const { Crypto } = require('vvlad1973-crypto');

In an ES module environment:

import { Crypto } from 'vvlad1973-crypto';

Example: Encrypting and Decrypting Text

const password = 'your-password';
const salt = 'your-salt';

// Create an instance of the Crypto class
const crypto = new Crypto(password, salt);

// Encrypt a text
const plainText = 'Hello, World!';
const encryptedText = crypto.encrypt(plainText);
console.log('Encrypted:', encryptedText);

// Decrypt the text
const decryptedText = crypto.decrypt(encryptedText);
console.log('Decrypted:', decryptedText);

API

new Crypto(password: string, salt: string, algorithm: string = 'SHA512', iterations: number = 1000, keyLength: number = 32, iv: number = 5)

password: The password used for key derivation.
salt: The salt used for key derivation.
algorithm: The hash algorithm to use for key derivation. Default is SHA512.
iterations: The number of iterations to use for key derivation. Default is 1000.
keyLength: The length of the derived key in bytes. Default is 32.
iv: The initialization vector for the AES encryption. Default is 5.
