Answer 1

Just to add to the pool of possibilities - Windows offers a range of built-in Cryptography functions. There probably is a Delphi wrapper for them as well, if it's not already included by default.

Among these functions is also a cryptographically strong random number generator. This is by far the best randomness you will get in software, because it seeds itself based on a very long list of factors. I'm not sure, but I suspect it will even use a hardware random number generator if you have one.

And if that's not enough, you can also try to sign up at the Quantum Random Bit Generator Service for some REALLY random values.
