[Question] How to test OS random generator

[Геннадий Забула]

I'm working on bringing support for UWP (https://github.com/weidai11/cryptopp/issues/143)

I've fixed all issues related the platform specific build. Except using windows OS Crypto API. 

I've reimplemented MicrosoftCryptoProvider class using BCrypt API. My question is as in title: how to test these changes?

cryptest tv all reports no errors.
