Types

type GaloisField448

type GaloisField448 struct {
	Limb *memguard.LockedBuffer
}

GaloisField448 is a field with a finite number of elements. The number depends on the word bits: 512/word_bits This should not be confunsed with the Field Element

func AddRaw32

func AddRaw32(x *GaloisField448, y *GaloisField448) *GaloisField448

AddRaw32 adds one galoisfield to another. For a 32 arch TODO: how should be error?

func AddRaw64

func AddRaw64(x *GaloisField448, y *GaloisField448) *GaloisField448

AddRaw64 adds one galoisfield to another. For a 32 arch

func Bias32

func Bias32(x *GaloisField448, amt int) *GaloisField448

Bias32 is

func NewGaloisField448

func NewGaloisField448(nlimbs int) *GaloisField448

NewGaloisField448 will return a newly created, empty field element TODO: use no escape

func NewGaloisField448FromBytes

func NewGaloisField448FromBytes(src []byte) *GaloisField448

NewGaloisField448FromBytes will return a newly created field element with the provided byte array TODO: use no escape

func SubRaw32

func SubRaw32(x *GaloisField448, y *GaloisField448) *GaloisField448

SubRaw32 subtracts one galoisfield to another. For a 32 arch TODO: how should be error?

func SubRaw64

func SubRaw64(x *GaloisField448, y *GaloisField448) *GaloisField448

SubRaw64 subtracts one galoisfield to another. For a 32 arch TODO: how should be error?

func (*GaloisField448) Copy

func (gf *GaloisField448) Copy() *GaloisField448

Copy copies one galoisfield to another.

func (*GaloisField448) Destroy

func (gf *GaloisField448) Destroy()

Destroy securely wipes and frees the underlying memory of the gf.Limb
