The signature is valid ? true

Stuff I used to make this

• FS NPMJS
• Crypto NPMJS

⚙️ How to use

1. Fork this repository
2. Import module

const hydrocrypto = require('hydrocrypto');
const fs = require('fs')

3. All fonc :

// Generate RSA key pair and save to files
cryptoUtils.generateRSAKeyPair();

// Encrypt and decrypt data
const plaintext = 'Hello World!';

// Generate encryption key
const encryptionKey = cryptoUtils.generateEncryptionKey();
console.log('Encryption key generated :', encryptionKey);

// Encrypt data
const encryptedData = cryptoUtils.encryptData(plaintext, encryptionKey);
console.log('Key figures :', encryptedData);

// Decrypt data
const decryptedData = cryptoUtils.decryptData(encryptedData, encryptionKey);
console.log('Deciphered data :', decryptedData);

// Sign and verify data
const keypub = fs.readFileSync('public-key.pub', 'utf-8');
const keypriv = fs.readFileSync('private-key.pem', 'utf-8');

// Sign data
const signature = cryptoUtils.signData(plaintext, keypriv);
console.log('Digital signature :', signature);

// Verify signature
const isSignatureValid = cryptoUtils.verifySignature(plaintext, signature, keypub);
console.log('The signature is valid ?', isSignatureValid);
