P2PKHInput class

An input for a Pay-to-Public-Key-Hash output (P2PKH). This contains the public key that should match the hash in the associated output. It is either signed or unsigned. The sign method can be used to sign the input with the corresponding ECPrivateKey or a signature can be added without checks using addSignature.

publicKey → ECPublicKey

final

runtimeType → Type

A representation of the runtime type of the object.

The script from the scriptSig bytes or null if the bytes do not represent a valid script.

sequence → int

signedSize → int?

The maximum total size when fully signed via the default hash type including any witness data of the input. If this is unknown, this is null. The actual signed size may be lower according to the data being encoded.

size → int

Obtains the cached size of the object

Methods

addSignature(ECDSAInputSignature insig) → P2PKHInput

Returns a new P2PKHInput with the ECDSAInputSignature added. Any existing signature is replaced.

override

checkKey(ECPrivateKey key) → ECPrivateKey

inherited

createInputSignature({required Transaction tx, required int inputN, required ECPrivateKey key, required Script scriptCode, SigHashType hashType = const SigHashType.all()}) → ECDSAInputSignature

Creates a signature for the input. Used by subclasses to implement signing.

inherited

filterSignatures(bool predicate(InputSignature insig)) → P2PKHInput

Removes signatures that the predicate returns false for. This is used to remove invalidated signatures.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

sign({required Transaction tx, required int inputN, required ECPrivateKey key, SigHashType hashType = const SigHashType.all()}) → P2PKHInput

Signs the input given the tx, input number (inputN) and a private key using the specifified hashType. Implemented by specific subclasses.

override

toBytes() → Uint8List

Obtains a cached Uint8List with data serialized for this object

inherited

toHex() → String

inherited

toString() → String

A string representation of this object.

inherited

write(Writer writer) → void

Override to write data into writer

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

match(RawInput raw) → P2PKHInput?

Checks if the RawInput matches the expected format for a P2PKHInput, with or without a signature. If it does it returns a P2PKHInput for the input or else it returns null.
