SecureRandom instance. Specifically, the resource will be read into an
InputStream and those bytes presented to the
SecureRandom.setSeed(byte[]) method. Note that this will simply supplement,
rather than replace, the existing seed. As such, it is always safe to set a seed
using this method (it never reduces randomness).seed - to use, or null if no additional seeding is needed
