Functions

func Schnorr

func Schnorr(suite abstract.Suite, private abstract.Scalar, msg []byte) ([]byte, error)

Schnorr creates a Schnorr signature from a msg and a private key. This signature can be verified with VerifySchnorr. It's also a valid EdDSA signature.

func VerifySchnorr

func VerifySchnorr(suite abstract.Suite, public abstract.Point, msg, sig []byte) error

VerifySchnorr verifies a given Schnorr signature. It returns nil iff the given signature is valid. NOTE: this signature scheme is malleable because the response's unmarshalling is done directly into a big.Int modulo (see nist.Int).
