Types

type ByteCycles 

type ByteCycles [][]byte

ByteCycles contains the cycles of a Byte encoding.

func NewByteCycles 

func NewByteCycles(in encoding.Byte) ByteCycles

NewByteCycles takes a Byte encoding as input and returns the corresponding ByteCycles object.

type DDT 

type DDT [256][256]int

DDT is a difference distribution table of a function.

func NewDDT 

func NewDDT(in encoding.Byte) *DDT

NewDDT generates the DDT of a function.

func (*DDT) Equals 

func (ddt *DDT) Equals(given *DDT) bool

Equals returns whether or not this DDT equals the given DDT.

func (*DDT) String
