🛠 Usage

CryptiaJS 🔐 CryptiaJS is a powerful and secure JavaScript library for encrypting and decrypting text and files using advanced encryption algorithms. Whether you're safeguarding sensitive data in web applications or adding encryption to your server-side projects, CryptiaJS is designed to be fast, reliable, and easy to use. ⚡

Your data stays protected—as long as you keep your encryption key private.

🚀 Installation

Install CryptiaJS via npm:

npm i cryptia

Or clone the GitHub repository:

git clone https://github.com/chukwunonsoprosper/cryptia
cd cryptia

Testing the Library

To test the library, run:

npm run test

Customizable Workspace

To spin up a customizable workspace, run:

npm run dev

You can also link workspace.js to your project directory to integrate CryptiaJS easily.

Example

/**
 * Import Cryptia and required dependencies.
 */
import Cryptia from '../cryptia.js'

// Initialize Cryptia with custom settings.
const cryptia = Cryptia({
    obfuscationLevel: 10,
    logging: false,
    preserveWhitespace: true
});

/**
 * Encrypt and decrypt text with a secure key.
 */
const plainText = 'This is a secret message.🤣😂';
const encryptionKey = 'MySecureKey1';

const encryptedResult = cryptia.encrypt(plainText, encryptionKey)
console.log('Encrypted Text:', encryptedResult.data);

const decryptedResult = cryptia.decrypt(encryptedResult.data, encryptionKey)
console.log('Decrypted Text:', decryptedResult.data);


// Encrypt a file
const fileEncryptResult = cryptia.encryptFile(
  '/path/to/file.txt',
  'secretKey',
  null,  // Callback function (optional)
  'output.encrypted'  // Output filename (optional)
);
console.log(`File encrypted to: ${fileEncryptResult.encryptedFilePath}`);

// Decrypt a file
const fileDecryptResult = cryptia.decryptFile(
  'output.encrypted',
  'secretKey',
  null,  // Callback function (optional)
  'decrypted_output.txt'  // Output filename (optional)
);
console.log(`File decrypted to: ${fileDecryptResult.decryptedFilePath}`);

Binary Data Encryption

// Encrypt binary data (like an image)
const imageBuffer = fs.readFileSync('image.png');
const encryptedBinary = cryptia.encryptBinary(imageBuffer, 'secretKey');
fs.writeFileSync('encrypted.bin', encryptedBinary.data);

// Decrypt binary data
const encryptedData = fs.readFileSync('encrypted.bin', 'utf-8');
const decryptedBinary = cryptia.decryptBinary(encryptedData, 'secretKey');
fs.writeFileSync('decrypted.png', decryptedBinary.data);

// Encrypt a large file using streams
await cryptia.encryptLargeFile(
  '/path/to/large-file.mp4',
  '/path/to/output-encrypted.bin',
  'secretKey'
);

// Decrypt a large file using streams
await cryptia.decryptLargeFile(
  '/path/to/output-encrypted.bin',
  '/path/to/recovered-file.mp4',
  'secretKey'
);

Install CLI globally

npm install -g cryptia
