Constructors

constructor

new Secp256k1PublicKey(hexInput): Secp256k1PublicKey
Create a new PublicKey instance from a HexInput, which can be a string or Uint8Array. This constructor validates the length of the provided signature data.
Parameters
- hexInput: HexInput
  A HexInput (string or Uint8Array) representing the signature data.
Returns Secp256k1PublicKey
Throws
Error if the length of the signature data is not equal to Secp256k1Signature.LENGTH.
Overrides PublicKey.constructor
- Defined in src/core/crypto/secp256k1.ts:36

Methods

bcsToBytes

bcsToBytes(): Uint8Array
Serializes a Serializable value to its BCS representation. This function is the TypeScript SDK equivalent of bcs::to_bytes in Move.

Returns Uint8Array
the BCS representation of the Serializable instance as a byte buffer.
Inherited from PublicKey.bcsToBytes
- Defined in src/bcs/serializer.ts:29

bcsToHex

bcsToHex(): Hex
Converts the BCS-serialized bytes of a value into a Hex instance. This function provides a Hex representation of the BCS-serialized data for easier handling and manipulation.

Returns Hex
A Hex instance with the BCS-serialized bytes loaded into its underlying Uint8Array.
Inherited from PublicKey.bcsToHex
- Defined in src/bcs/serializer.ts:40

deserialize

deserialize(deserializer): Secp256k1Signature
Deserializes a Secp256k1Signature from the provided deserializer. This function allows you to reconstruct a Secp256k1Signature object from its serialized byte representation.
Parameters
- deserializer: Deserializer
  The deserializer instance used to read the serialized data.
Returns Secp256k1Signature
- Defined in src/core/crypto/secp256k1.ts:95

serialize

serialize(serializer): void
Serializes the data into a byte array using the provided serializer. This function is essential for converting data into a format suitable for transmission or storage.
Parameters
- serializer: Serializer
  The serializer instance used to convert the data.
Returns void
Overrides PublicKey.serialize
- Defined in src/core/crypto/secp256k1.ts:84

toString

toString(): string
Get the public key as a hex string with a 0x prefix.

Returns string
The public key in hex format.
Inherited from PublicKey.toString
- Defined in src/core/crypto/publicKey.ts:44

toStringWithoutPrefix

toStringWithoutPrefix(): string
Returns the hex string representation of the Serializable value without the 0x prefix.

Returns string
the hex format as a string without 0x prefix.
Inherited from PublicKey.toStringWithoutPrefix
- Defined in src/bcs/serializer.ts:49

toUint8Array

toUint8Array(): Uint8Array
Get the data as a Uint8Array representation.

Returns Uint8Array
Uint8Array representation of the data.
Overrides PublicKey.toUint8Array
- Defined in src/core/crypto/secp256k1.ts:70

verifySignature

verifySignature(args): boolean
Verifies a Secp256k1 signature against the public key.

This function checks the validity of a signature for a given message, ensuring that the signature is canonical as a malleability check.
Parameters
- args: VerifySignatureArgs
  The arguments for verifying the signature.
Returns boolean
Overrides PublicKey.verifySignature
- Defined in src/core/crypto/secp256k1.ts:56

`Static`deserialize

deserialize(deserializer): Secp256k1PublicKey
Parameters
- deserializer: Deserializer
Returns Secp256k1PublicKey
- Defined in src/core/crypto/secp256k1.ts:100

`Static`isInstance

isInstance(publicKey): publicKey is Secp256k1PublicKey
Determines if the provided public key is a valid instance of a Secp256k1 public key. This function checks for the presence of a "key" property and validates the length of the key data.
Parameters
- publicKey: PublicKey
  The public key to validate.
Returns publicKey is Secp256k1PublicKey
A boolean indicating whether the public key is a valid Secp256k1 public key.
- Defined in src/core/crypto/secp256k1.ts:124

`Static`isPublicKey

isPublicKey(publicKey): publicKey is Secp256k1PublicKey
Determine if the provided public key is an instance of Secp256k1PublicKey.
Parameters
- publicKey: PublicKey
  The public key to check.
Returns publicKey is Secp256k1PublicKey
Deprecated
use instanceof Secp256k1PublicKey instead
- Defined in src/core/crypto/secp256k1.ts:113

Properties

`Static` `Readonly`LENGTH

LENGTH: number = 65

The length of the Secp256k1 public key in bytes.
