Insecure Random Fortify Math.random alternative

Math.random.polyfill.js

function generateRandom() {
    // Generate a secure random 32-bit unsigned integer
    const randomBuffer = new Uint32Array(1);
    window.crypto.getRandomValues(randomBuffer);

    // Convert the random integer to a floating-point number between 0 (inclusive) and 1 (exclusive)
    return randomBuffer[0] / (0xFFFFFFFF + 1);
}

for nodejs use below code

const crypto = require("crypto");

function generateRandom() {
  // Generate a secure random 32-bit unsigned integer
  const randomBuffer = new Uint32Array(1);
  crypto.webcrypto.getRandomValues(randomBuffer);

  // Convert the random integer to a floating-point number between 0 (inclusive) and 1 (exclusive)
  return randomBuffer[0] / (0xFFFFFFFF + 1);
}

console.log(generateRandom()); // Example usage
