求还原JD-GUI反编译后的一段MD5加密代码

Question

public static String b(String paramString)
  {
    MessageDigest localMessageDigest = null;
    try
    {
      localMessageDigest = MessageDigest.getInstance("MD5");
      localMessageDigest.reset();
      localMessageDigest.update(paramString.getBytes("UTF-8"));
      label22: arrayOfByte = localMessageDigest.digest();
      localStringBuffer = new StringBuffer();
      i = 0;
      if (i >= arrayOfByte.length)
        return localStringBuffer.toString();
    }
    catch (UnsupportedEncodingException localUnsupportedEncodingException)
    {
      byte[] arrayOfByte;
      StringBuffer localStringBuffer;
      int i;
      while (true)
        localUnsupportedEncodingException.printStackTrace();
      if (Integer.toHexString(0xFF & arrayOfByte[i]).length() == 1)
        localStringBuffer.append("0").append(Integer.toHexString(0xFF & arrayOfByte[i]));
      while (true)
      {
        i++;
        break;
        localStringBuffer.append(Integer.toHexString(0xFF & arrayOfByte[i]));
      }
    }
    catch (NoSuchAlgorithmException localNoSuchAlgorithmException)
    {
      break label22;
    }
  }

你用jad试试，接合两个反编译的参考，应该可以还原
