Methods

derive(List<int> chainCode, [List<int>? message]) → (SchnorrkelPublicKey, List<int>)

Derives a new Schnorrkel public key and chain code using hierarchical deterministic key derivation (HDKD).

dleqVerify(MerlinTranscript script, VRFInOut out, VRFProof proof, {bool isKusamaVRF = true}) → bool

Verifies a Discrete Logarithm Equality (DLEQ) proof for a Verifiable Random Function (VRF) output.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toBytes() → List<int>

Converts the Schnorrkel public key to a byte representation.

toPoint() → RistrettoPoint

Converts the Schnorrkel public key to a RistrettoPoint point.

toString() → String

A string representation of this object.

inherited

verify(SchnorrkelSignature signature, MerlinTranscript signingContextScript) → bool

Verifies a Schnorrkel signature using the public key and a transcript.

vrfHash(MerlinTranscript script, {List<int>? keyBytes}) → RistrettoPoint

Computes a VRF (Verifiable Random Function) hash using a transcript.

vrfVerify(MerlinTranscript script, VRFPreOut output, VRFProof proof, {MerlinTranscript? verifyScript}) → bool

Verifies a Verifiable Random Function (VRF) output and its proof.

Operators

operator ==(Object other) → bool

The equality operator.
