> Add a default factory method to provide simpler API and better hardware
> random.
> OpensslCryptoRandom uses hardware random number generator if hardware
> supports.
> Hardware random number generators are almost always better to use than a
> software based generator. Hardware generators are often called True Random
> Number generators (TRNG) or Non-Deterministic Random Number Generators since
> they don't rely on the deterministic behavior of executing software
> instructions. Their bits streams are nearly always indistinguishable from
> random streams, and their entropy is always nearly 100%.
> Modern Intel CPUs(3rd generation Core i5 or i7 processor (Ivy Bridge) or
> above) do support random number generator, it is better to provide a
> default API(openssl implementation) for the client user.
> {code}
> // By default, use True Random Number Generator (hardware random)
> // Simpler API. client code is clean.
> CryptoRandom random = CryptoRandomFactory.getCryptoRandom();
> byte[] key = new byte[16];
> random.nextBytes(key);
> random.close();
> {code}
