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
