crypto.subtle.digest({ name: 'SHA-256' }, data).then(function(buffer) {
  var bytes = new Uint8Array(buffer);
  var res = '';
  for (var i = 0; i < bytes.length; i++) {
    var byte = bytes[i].toString(16);
    byte = (byte.length < 2) ? ('0' + byte) : byte;
    res += byte;
  }
  console.log(res);
});
