BitcoinSigner class

The BitcoinSigner class encapsulates functionality for signing Bitcoin messages, transactions, and Schnorr-based transactions using ECDSA (Elliptic Curve Digital Signature Algorithm) and related cryptographic operations.

Constructors

BitcoinSigner.fromKeyBytes(List<int> privateKeyBytes)

Factory constructor for creating a BitcoinSigner from private key bytes.

factory

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

signingKey → EcdsaSigningKey

The ECDSA signing key associated with this Bitcoin signer.

final

verifyKey → BitcoinVerifier

Returns a BitcoinVerifier instance associated with the verification key derived from the signer's private key.

no setter

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

signMessage(List<int> message, String messagePrefix) → List<int>

Signs a given message using the ECDSA deterministic signature scheme. The message is first hashed and then signed using the private key.

signSchnorrTransaction(List<int> digest, {required List tapScripts, required bool tweak}) → List<int>

Signs a given Schnorr-based transaction digest using the Schnorr signature scheme.

signTransaction(List<int> digest) → List<int>

Signs a given transaction digest using the ECDSA deterministic signature scheme. The signature is adjusted for low-S encoding and verified against the public key.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
