SecureRandom uses straightforward implementations inherited from Random but in the process does double the memory allocations necessary. The delegation to SecureRandom.engineNextBytes does not provide `int` or `long` values, the caller must allocate a byte array and assemble the value itself. So added an implementation in SecureRandom that call nextBytes(8 bytes) and then convert that to a long.
