Class: SignatureProof ​

A signature proof represents a signature together with its public key and the public key's merkle path. It is used as the proof for transactions.

Constructors ​

new SignatureProof() ​

new SignatureProof(): SignatureProof

Returns ​

SignatureProof

Properties ​

publicKey ​

readonly publicKey: ES256PublicKey | PublicKey

The embedded public key.

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1830

signature ​

readonly signature: ES256Signature | Signature

The embedded signature.

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1834

Methods ​

free() ​

free(): void

Returns ​

void

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1774

isSignedBy() ​

isSignedBy(sender): boolean

Checks if the signature proof is signed by the provided address.

Parameters ​

• sender: Address

Returns ​

boolean

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1821

serialize() ​

serialize(): Uint8Array

Serializes the proof to a byte array, e.g. for assigning it to a transaction.proof field.

Returns ​

Uint8Array

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1826

verify() ​

verify(data): boolean

Verifies the signature proof against the provided data.

Parameters ​

• data: Uint8Array

Returns ​

boolean

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1815

multiSig() ​

static multiSig(signer_key, public_keys, signature): SignatureProof

Creates a Ed25519/Schnorr signature proof for a multi-sig signature. The public keys can also include ES256 keys.

Parameters ​

• signer_key: PublicKey

• public_keys: (ES256PublicKey | PublicKey)[]

• signature: Signature

Returns ​

SignatureProof

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1790

singleSig() ​

static singleSig(public_key, signature): SignatureProof

Creates a Ed25519/Schnorr signature proof for a single-sig signature.

Parameters ​

• public_key: PublicKey

• signature: Signature

Returns ​

SignatureProof

Defined in ​

@nimiq/core/types/wasm/web.d.ts:1781

webauthnMultiSig() ​

static webauthnMultiSig(signer_key, public_keys, signature, authenticator_data, client_data_json): SignatureProof

Creates a Webauthn signature proof for a multi-sig signature.

Parameters ​

• signer_key: ES256PublicKey | PublicKey

• public_keys: (ES256PublicKey | PublicKey)[]

• signature: ES256Signature | Signature

• authenticator_data: Uint8Array

• client_data_json: Uint8Array

Returns ​

Parameters ​

• public_key: ES256PublicKey | PublicKey

• signature: ES256Signature | Signature

• authenticator_data: Uint8Array

• client_data_json: Uint8Array

Returns ​
