📦 Installation

npm install my-crypto-tool

const MyCrypto = require('my-crypto-tool');

const secret_key = process.env.SECRET_KEY || 'my_key';
const myCrypto = new MyCrypto(secret_key);

// Example can be object, string, or number
// const example = { name: 'John Doe', age: 30 };
// const example = "hello";

const example = { name: 'John Doe', age: 30 };

// Encrypt
const encrypted = myCrypto.encrypt(example);
console.log('Encrypted:', encrypted);

// Decrypt
const decrypted = myCrypto.decrypt(encrypted);
console.log('Decrypted:', decrypted);
