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
-

int> privateKeyBytes) -
Factory constructor for creating a BitcoinSigner from private key bytes.

Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- 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.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
signBcHTransaction(
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.
-
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> ? auxRand}) → List<int> - Signs a given Schnorr-based transaction digest using the Schnorr signature scheme.
-
signSchnorrTx(
List< int> digest, {List<int> ? tweak, List<int> ? auxRand}) → 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.

Object other) → bool -
The equality operator.
