Types

type SM2P256Element

type SM2P256Element struct {
	// contains filtered or unexported fields
}

SM2P256Element is an integer modulo 2^256 - 2^224 - 2^96 + 2^64 - 1.

The zero value is a valid zero element.

func (*SM2P256Element) Add

func (e *SM2P256Element) Add(t1, t2 *SM2P256Element) *SM2P256Element

Add sets e = t1 + t2, and returns e.

func (*SM2P256Element) Bytes

func (e *SM2P256Element) Bytes() []byte

Bytes returns the 32-byte big-endian encoding of e.

func (*SM2P256Element) Equal

func (e *SM2P256Element) Equal(t *SM2P256Element) int

Equal returns 1 if e == t, and zero otherwise.

func (*SM2P256Element) Invert

func (e *SM2P256Element) Invert(x *SM2P256Element) *SM2P256Element

Invert sets e = 1/x, and returns e.

If x == 0, Invert returns e = 0.

func (*SM2P256Element) IsZero

func (e *SM2P256Element) IsZero() int

IsZero returns 1 if e == 0, and zero otherwise.

func (*SM2P256Element) Mul

func (e *SM2P256Element) Mul(t1, t2 *SM2P256Element) *SM2P256Element

Mul sets e = t1 * t2, and returns e.

func (*SM2P256Element) One

func (e *SM2P256Element) One() *SM2P256Element

One sets e = 1, and returns e.

func (*SM2P256Element) Select

func (v *SM2P256Element) Select(a, b *SM2P256Element, cond int) *SM2P256Element

Select sets v to a if cond == 1, and to b if cond == 0.

func (*SM2P256Element) Set

func (e *SM2P256Element) Set(t *SM2P256Element) *SM2P256Element

Set sets e = t, and returns e.

func (*SM2P256Element) SetBytes

func (e *SM2P256Element) SetBytes(v []byte) (*SM2P256Element, error)

SetBytes sets e = v, where v is a big-endian 32-byte encoding, and returns e. If v is not 32 bytes or it encodes a value higher than 2^256 - 2^224 - 2^96 + 2^64 - 1, SetBytes returns nil and an error, and e is unchanged.

func (*SM2P256Element) Square

func (e *SM2P256Element) Square(t *SM2P256Element) *SM2P256Element

Square sets e = t * t, and returns e.

func (*SM2P256Element) Sub

func (e *SM2P256Element) Sub(t1, t2 *SM2P256Element) *SM2P256Element

Sub sets e = t1 - t2, and returns e.

type SM2P256OrderElement

func (*SM2P256OrderElement) One

func (e *SM2P256OrderElement) One() *SM2P256OrderElement

One sets e = 1, and returns e.

func (*SM2P256OrderElement) Select

func (v *SM2P256OrderElement) Select(a, b *SM2P256OrderElement, cond int) *SM2P256OrderElement
