I mean just for the love of God don’t spin up something on your company’s infrastructure that accepts file uploads.
Just don’t.
If you’re reading this and going “well, it’s just internal,” or “well, it doesn’t do much it just accepts this exact file type.” My god. Ask your CISA. And if they’re okay with it, cool. That’s on them.
Unless your whole business is transferring files, don’t. And even then… Don’t.
And if you’re still confused, the answer is to use another company’s infrastructure for this. Use Azure. Use AWS. Use Google cloud or even g suites. Don’t accept that liability. Let the trillionaires do it.





My first method eliminates waiting to see if your students code runs fast enough. Unless complexity is part of the assignment, I’d still say go for the hash.
It’s also less work for the professor/grader.
