OpenSSL-3.+ how to configure [random]?

[Dr Paul Dale]

I'm pretty sure the underlying problem is that there is a call to 
RAND_set_rand_method() or RAND_set_rand_engine() occurring (likely the 
latter).

These completely replace the built in RNG infrastructure with the 
RAND_METHOD/engine.  If the engine then fails to produce output for any 
reason, the observed results will present.

Adding the RDRAND engine again replaces the RAND_METHOD and things begin 
working.


I've no idea why the PKCS#11 engine has stopped working with 3.0. It 
wasn't meant to.
