type SuiteBLS12381 

type SuiteBLS12381 struct {
	Suite
	kyber.Group
}

SuiteBLS12381 is an adapter that implements the suites.Suite interface so that bls12381 can be used as a common suite to generate key pairs for instance but still preserves the properties of the pairing (e.g. the Pair function).

It's important to note that the Point function will generate a point compatible with public keys only (group G2) where the signature must be used as a point from the group G1.

func NewSuiteBLS12381 

func NewSuiteBLS12381() *SuiteBLS12381

NewSuiteBLS12381 makes a new BN256 suite

func (*SuiteBLS12381) Point 

func (s *SuiteBLS12381) Point() kyber.Point

Point generates a point from the G2 group that can only be used for public keys

func (*SuiteBLS12381) PointLen 

func (s *SuiteBLS12381) PointLen() int

PointLen returns the length of a G2 point

func (*SuiteBLS12381) Scalar 

func (s *SuiteBLS12381) Scalar() kyber.Scalar

Scalar generates a scalar

func (*SuiteBLS12381) ScalarLen 

func (s *SuiteBLS12381) ScalarLen() int

ScalarLen returns the lenght of a scalar

func (*SuiteBLS12381) String 

func (s *SuiteBLS12381) String() string

String returns the name of the suite
