type SuiteBLS12381 

type SuiteBLS12381 struct {

}

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.
