TeaEncryptor

A TeaEncryptor for encrypting and decrypting text into numbers using a custom character set and offset key.

Installation

You can install TeaEncryptor via npm:

npm install tea-enc

Usage

import TeaEncryptor from 'tea-enc';

// Create a new TeaEncryptor instance
const encryptor = new TeaEncryptor();

// Encrypt text
const encryptedText = encryptor.enc('Hello World');

// Decrypt text
const decryptedText = encryptor.dec(encryptedText);

console.log('Encrypted:', encryptedText);
console.log('Decrypted:', decryptedText);

Running Tests

You can run tests using npm:

npm run test

This will run the test script located at tests/test.js, which will encrypt and decrypt a sample text and output the results.

Expected output:

> [email protected] test
> node tests/test.js
