inherited
recoverId({required List<int> hash, required ECDSAPublicKey publicKey}) → int?
find correct recovery id from signature.
recoverPublicKey(List<int> hash, ProjectiveECCPoint generator, int recId) → ECDSAPublicKey
Recovers public key from the ECDSA signature and a hash of the message.
recoverPublicKeys(List<int> hash, ProjectiveECCPoint generator) → List<ECDSAPublicKey>
Recovers public keys from the ECDSA signature and a hash of the message.
toBytes(int baselen) → List<int>
convert signature to bytes.
toString() → String
A string representation of this object.
