Cryptoswiftjs NPM

CryptoSwiftJS 🔐

A secure AES-256-GCM encryption/decryption library using Argon2 password hashing.

🚀 Features

✅ Uses AES-256-GCM (high security)
✅ Password-based key derivation using Argon2id
✅ Uses random salts & IVs for stronger encryption
✅ Easy to use & lightweight

📚 Installation

Install via npm:

npm install cryptoswiftjs

Or with yarn:

yarn add cryptoswiftjs

🔧 Usage

Encrypt Data

const { encrypt } = require('cryptoswiftjs');

const message = "Hello, Secure World!";
const password = "mySuperStrongPassword123";

(async () => {
    const encrypted = await encrypt(message, password);
    console.log("Encrypted:", encrypted);
})();

Decrypt Data

const { decrypt } = require('cryptoswiftjs');

(async () => {
    const encryptedData = "your_encrypted_data_here";
    const decrypted = await decrypt(encryptedData, "mySuperStrongPassword123");
    console.log("Decrypted:", decrypted);
})();

🛠️ How It Works

Password-Based Key Derivation
- Uses Argon2id to generate a 32-byte key from the password.
- Includes random salts for enhanced security.
AES-256-GCM Encryption
- Encrypts data with a random IV using AES-256-GCM.
- Generates an authentication tag to prevent tampering.
Secure Decryption
- Uses the same password to derive the key and decrypt the data.
- Validates the authentication tag to ensure integrity.
