type P224Element source
Methods
Addsource
func (e *P224Element) Add(t1, t2 *P224Element) *P224ElementAdd sets e = t1 + t2, and returns e.
Bytessource
func (e *P224Element) Bytes() []byteBytes returns the 28-byte big-endian encoding of e.
Equalsource
func (e *P224Element) Equal(t *P224Element) intEqual returns 1 if e == t, and zero otherwise.
