Grab the keyword OpenSSL at a glance. If it is a Windows 64-bit system, download the “Win64 OpenSSL” installer.
Win32/Win64 OpenSSL Installer for Windows – Shining Light Productions (slproweb.com)
https://slproweb.com/products/Win32OpenSSL.html Directly install openssl installation package It is the fastest and most convenient method.
Just download the Win64 openssl version and select the folder.
Next
“Select Additional Tasks” allows you to choose where to copy the OpenSSL dll. It is recommended not to copy it to the system directory. If the openssl version used by other software is different from the version you installed, the software may not be usable. (This explanation is referenced from: http://t.csdn.cn/zDOTd)

If you don’t have money (donation requires you to donate money), you can’t choose anything.
Make sure environment variables and CMD are accessible
