public final class Anubis extends BaseCipher
Anubis is a 128-bit block cipher that accepts a variable-length key. The cipher is a uniform substitution-permutation network whose inverse only differs from the forward operation in the key schedule. The design of both the round transformation and the key schedule is based upon the Wide Trail strategy and permits a wide variety of implementation trade-offs.
