Script Preparation code:

var data = new Uint32Array(10*1024*1024);
var dataBuffer = new Uint8Array(data);
  
  
  // src: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest
  function hex(buffer) {
    var hexCodes = [];
    var view = new DataView(buffer);
    for (var i = 0; i < view.byteLength; i += 4) {
      // Using getUint32 reduces the number of iterations needed (we process 4 bytes each time)
      var value = view.getUint32(i)
      // toString(16) will give the hex representation of the number without padding
      var stringValue = value.toString(16)
      // We use concatenation and slice for padding
      var padding = '00000000'
      var paddedValue = (padding + stringValue).slice(-padding.length)
      hexCodes.push(paddedValue);
    }
  
    // Join all the hex strings into one
    return hexCodes.join("");
  }
