44=head1 WARNING
45
46The best known result (early 2017) against Spritz is a distinguisher
47attack on 2**44 outputs with multiple keys/IVs, and on 2**60 outputs with
48a single key (see doi:10.1007/978-3-662-52993-5_4 for details). These are
49realistic attacks, so Spritz needs to be considered broken, although for
50low data applications it should still be useful.
