I was wondering is there a way to have a cryptographically secure random in Excels. I know that there are random functions like randbetween(), Rand() and such, but those don't use /dev/random or any other cryptographically secure source that there is for windows (I hear https://en.wikipedia.org/wiki/CryptGenRandom is deprecated). Is there a very fast and cryptographically secure random number generator for VBA? Something like https://docs.microsoft.com/en-us/dot...tframework-4.8 or a way to import it for fast randomnumber generator?
