+/**
+
+
+From "Dismantling iclass":
+ This section describes in detail the built-in key diversification algorithm of iClass.
+ Besides the obvious purpose of deriving a card key from a master key, this
+ algorithm intends to circumvent weaknesses in the cipher by preventing the
+ usage of certain ‘weak’ keys. In order to compute a diversified key, the iClass
+ reader first encrypts the card identity id with the master key K, using single
+ DES. The resulting ciphertext is then input to a function called hash0 which
+ outputs the diversified key k.
+
+ k = hash0(DES enc (id, K))
+
+ Here the DES encryption of id with master key K outputs a cryptogram c
+ of 64 bits. These 64 bits are divided as c = x, y, z [0] , . . . , z [7] ∈ F 82 × F 82 × (F 62 ) 8
+ which is used as input to the hash0 function. This function introduces some
