📦 Installation

npm install aes-object

📖 Usage

import { decryptObject, encryptObject } from 'aes-object';

const secretKey = 'mySecretKey';
const data = { message: Buffer.from('Hello, world!') };

const encrypted = encryptObject({ input: data, secretKey });
console.log('Encrypted:', encrypted); // S7WhaSK63RuL3r+AQ5cG5AMSG9r4356DX1wUXZXgTUgeh19GlTl1wbsW1+jZUBqJl0pBKDMBBxAKDrTOqBbD0U5clObURb2OyRCKsf1LtqM=

const decrypted = decryptObject({ input: encrypted, secretKey });
console.log('Decrypted:', decrypted); // { message: <Buffer 48 65 6c 6c 6f 2c 20 77 6f 72 6c 64 21> }

console.log('Message:', decrypted.message.toString()); // Hello, world!;

API

/**
 * Encrypts an object using AES encryption.
 *
 * @template T - The type of the input object.
 * @param {AesEncryptObjectParams<T>} params - The encryption parameters.
 * @param {T} params.input - The object to be encrypted.
 * @param {string} params.secretKey - The secret key for encryption.
 * @param {string} [params.iv] - The initialization vector (IV) for encryption. If not provided, a random IV will be generated.
 * @returns {string} The encrypted data as a string in Base64 format.
 * @throws {TypeError} If the input is not an object.
 */

/**
 * Decrypts an AES-encrypted string back into an object.
 *
 * @template T - The expected type of the decrypted object.
 * @param {AesDecryptObjectParams} params - The decryption parameters.
 * @param {string} params.input - The encrypted string in Base64 format.
 * @param {string} params.secretKey - The secret key used for decryption.
 * @param {string} [params.iv] - The initialization vector (IV) used for decryption. If not provided, it uses the IV from the encrypted data.
 * @returns {T | null} The decrypted object if successful, or null if decryption fails.
