Double Seed Encryption

Double Seed Encryption is a lightweight Node.js library for encrypting and decrypting data using the AES-256-CBC algorithm with a double-seed-based key generation approach. This ensures robust data security, making it suitable for a wide range of applications.

Features

Double-Seed Security: Combines two seeds to generate a strong encryption key. Data Type Support: Works with text, strings, and JSON objects. AES-256-CBC Encryption: Provides a secure and widely-used encryption algorithm. No External Dependencies: Uses the built-in Node.js crypto module. Simple API: Easy-to-use functions for encryption and decryption.

Installation

Install the package using NPM:

bash

npm install double-seed-encryption

Usage

Encrypting and Decrypting Text Data

javascript

const { encrypt, decrypt } = require('double-seed-encryption');

// Define seeds const seed1 = 'myFirstSeed'; const seed2 = 'mySecondSeed';

// Data to encrypt const textData = 'This is some sensitive information';

// Encrypt data const encryptedData = encrypt(textData, seed1, seed2); console.log('Encrypted Data:', encryptedData);

// Decrypt data const decryptedData = decrypt(encryptedData, seed1, seed2); console.log('Decrypted Data:', decryptedData);

Encrypting and Decrypting JSON Data

javascript

const jsonData = { username: 'testUser', permissions: 'read', 'write' };

// Encrypt JSON object const encryptedJson = encrypt(jsonData, seed1, seed2); console.log('Encrypted JSON:', encryptedJson);

// Decrypt JSON object const decryptedJson = decrypt(encryptedJson, seed1, seed2); console.log('Decrypted JSON:', decryptedJson);

API Reference

encrypt(data, seed1, seed2)

data: The data to encrypt (string, text, or JSON object). seed1: The first seed used for key generation. seed2: The second seed used for key generation. Returns: An encrypted string in the format IV:EncryptedData.

decrypt(encryptedData, seed1, seed2)

encryptedData: The encrypted string in the format IV:EncryptedData. seed1: The first seed used during encryption. seed2: The second seed used during encryption. Returns: The original data (string or JSON object).

Example Use Cases

Secure API payloads with JSON data. Encrypt configuration files or sensitive application data. Protect user credentials during transmission.

Testing

Run tests to ensure everything works correctly:

bash

npm test
