Is it possible to validate a downloaded file in Jmeter?

I have a REST service that I'm currently testing in J-Meter. I have a number of endpoints that I'm currently testing, they do the following:

1. Allow the upload of files to the service
2. Return a list of available files
3. Allow the download of files from the list

I have tests in J-Meter that test all this functionality, and it works well. But I'm wondering if it's possible to verify that the files I uploaded are exactly the same as the files I've downloaded in J-Meter? Is this possible? Maybe by hashing both files and comparing perhaps?
