820           algorithm.
821 
822           Rijndael appears to be consistently a very good performer in
823           both hardware and software across a wide range of computing
824           environments regardless of its use in feedback or non-feedback
825           modes. Its key setup time is excellent, and its key agility is
826           good. Rijndael's very low memory requirements make it very well
827           suited for restricted-space environments, in which it also
828           demonstrates excellent performance. Rijndael's operations are
829           among the easiest to defend against power and timing attacks.
