Haven't seen this be posted anywhere yet, I installed OpenSSL for windows.
Getting the same error installing Scrypt
Python3, Windows 10. Tried using a different version of python but with no avail.
Running setup.py install for scrypt ... error

Stackoverflow won't let me post cause it says most of my post is code but it's just the error log so I'm posting this so it'll let me post. I think I've giffen sufficient information
Cannot open include file: 'openssl/aes.h': No such file or directory
You would need the OpenSSL development files to build that library. This answer seems related: How to use OpenSSL with Visual Studio
Failing that, it looks like scrypt has wheels (precompiled binary packages) for Python 3.8 on Windows: https://pypi.org/project/scrypt/#files
So if it's possible for you to switch to Python 3.8, that would also likely solve your problem.
