import CryptoMD5 from "crypto-js/md5";
import CryptoLatin1Encoder from "crypto-js/enc-latin1";

function handleUploadClick(e: React.ChangeEvent<HTMLInputElement>) {
  if (!e.target.files) {
    return;
  }
  const selectedFile = e.target.files[0];

  const reader = new FileReader();

  reader.onloadend = (e) => {
    // Calculate md5 by using CryptoJS after content loaded.
    // https://developer.mozilla.org/en-US/docs/Web/API/FileReader
    const gotMD5 = CryptoMD5(
      CryptoLatin1Encoder.parse(e.target!.result as string)
    );
    const hexMD4 = gotMD5.toString();
  };
}
