Uses IPP-Crypto pseudo random number generator if none of those instructions are supported
Minor typo fixes

I think we should support systems without RDRAND and/or RDSEED instructions. @faberga, @fdiasmor, @justalittlenoob opinions?

fdiasmor commented 2 years ago

@skmono It is not unreasonable. I'd suggest to at least add a pragma warning compilation message. What is the impact in the generic scenarios to assume the default behavior (neither RDRAND nor RDSEED) to resort to PRNG?
