Hi Tharindu, I checked your `readMD5(InputStream inputStream)` method and it is working as expected. The problem is with the inputStream you are passing into the method.
Please verify that you are not passing the *same inputStream* on the second time. Because once it is utilized pos has reached the end. So, the second time you are creating a hash of an empty stream.
