Random Salt Generation

The salt comes from the browser's secure random number generator, then gets converted into hexadecimal so it can be displayed on the page.

function randHex(bytes) {
  const arr = new Uint8Array(bytes);
  crypto.getRandomValues(arr);

  return Array.from(arr)
    .map((b) => b.toString(16).padStart(2, '0'))
    .join('');
}

async function genSalt() {
  currentSalt = randHex(32);
  await updateSalted();
}
