为什么在系统DLL中Powershell和32bit-Python之间获得不同的SHA1散列?

I'm trying to calculate SHA1 hash values in Python against binary files for later comparison. To make sure things are working, I used several methods to check the validity of my result. And, I'm glad I did. Powershell and Python return different values. 7zip's SHA1 function agrees with Powershell's results and Microsoft's FCIV agrees with Python's results.I'm trying to calculate SHA1 hash values in Pyt
