Class Secp256k1PublicKey

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.

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

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

toUint8Array

• toUint8Array(): Uint8Array

• Get the data as a Uint8Array representation.

  Returns Uint8Array

  Uint8Array representation of the data.

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

Staticdeserialize

• deserialize(deserializer): Secp256k1PublicKey

• Parameters

  • deserializer: Deserializer

  Returns Secp256k1PublicKey

StaticisInstance

• 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.

StaticisPublicKey

• 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
