Need conversion m

Answer 1

atob() then charCodeAt() will give you binary & toString(16) will give you hex.

function base64ToHex(str) {
  const raw = atob(str);
  let result = '';
  for (let i = 0; i < raw.length; i++) {
    const hex = raw.charCodeAt(i).toString(16);
    result += (hex.length === 2 ? hex : '0' + hex);
  }
  return result.toUpperCase();
}

console.log(base64ToHex("oAAABTUAAg=="));
