Summary

SecureRandom nextLong memory usage enhancement

Problem

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.

Solution

Add an implementation in SecureRandom that call nextBytes(8 bytes) and then convert that to a long
