Implementierung einer Hashfunktion in JavaScript

// Using built-in Web Crypto API for SHA-256 hash
async function sha256Hash(message) {
  // Convert string to ArrayBuffer
  const msgBuffer = new TextEncoder().encode(message);
  // Use SubtleCrypto API to calculate hash
  const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);
  // Convert ArrayBuffer to hexadecimal string
  const hashArray = Array.from(new Uint8Array(hashBuffer));
  const hashHex = hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
  return hashHex;
}

// Usage example
sha256Hash('Hello, LightNode!').then(hash => console.log(hash));
// Output will be the SHA-256 hash of "Hello, LightNode!"
