Constructors

constructor

new Secp256k1PublicKey(hexInput): Secp256k1PublicKey
Create a new PublicKey instance from a Uint8Array or String.
Parameters
- hexInput: HexInput
  A HexInput (string or Uint8Array)
Returns Secp256k1PublicKey
Overrides PublicKey.constructor
- Defined in src/core/crypto/secp256k1.ts:33

Properties

`Private` `Readonly` key

key: Hex

`Static` `Readonly` LENGTH

LENGTH: number = 65

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:27

bcsToHex

bcsToHex(): Hex
Helper function to get a value's BCS-serialized bytes as a Hex instance.

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:37

serialize

serialize(serializer): void
Parameters
- serializer: Serializer
Returns void
Overrides PublicKey.serialize
- Defined in src/core/crypto/secp256k1.ts:69

toString

toString(): string
Get the public key as a hex string with a 0x prefix e.g. 0x123456...

Returns string
Inherited from PublicKey.toString
- Defined in src/core/crypto/publicKey.ts:36

toUint8Array

toUint8Array(): Uint8Array
Get the raw public key bytes

Returns Uint8Array
Overrides PublicKey.toUint8Array
- Defined in src/core/crypto/secp256k1.ts:61

verifySignature

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

Note signatures are validated to be canonical as a malleability check
Parameters
- args: VerifySignatureArgs
Returns boolean
Overrides PublicKey.verifySignature
- Defined in src/core/crypto/secp256k1.ts:49

`Static` deserialize

deserialize(deserializer): Secp256k1PublicKey
Parameters
- deserializer: Deserializer
Returns Secp256k1PublicKey
- Defined in src/core/crypto/secp256k1.ts:73

`Static` isPublicKey

isPublicKey(publicKey): publicKey is Secp256k1PublicKey
Parameters
- publicKey: PublicKey
Returns publicKey is Secp256k1PublicKey
Deprecated
use instanceof Secp256k1PublicKey instead
- Defined in src/core/crypto/secp256k1.ts:84
