I need to create my own crypto service provider for Windows and access it through the Crypto Api or other. There is very little information about this on the Internet, could you tell me where to look for information and where to even start?
(All this is done for educational purposes)
Thank you in advance!

I created a dll library and placed the path of this dll in the .reg file and launched it, this csp appeared in the registry and what should I do next so that I can open the context so that I can perform any cryptographic operations through the Crypto Api?
I would be glad for any information, thanks!
