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: {
        message: HexInput;
        signature: Secp256k1Signature;
    }

    The arguments for verifying the signature.

    • message: HexInput

      The message that was signed.

    • signature: Secp256k1Signature

      The signature to verify against the public key.

  Returns boolean

verifySignatureAsync

• verifySignatureAsync(args): Promise<boolean>

• Note: Secp256k1Signatures can be verified syncronously.

  Verifies the provided signature against the given message. This function helps ensure the integrity and authenticity of the message by confirming that the signature is valid.

  Parameters

  • args: {
        aptosConfig: AptosConfig;
        message: HexInput;
        signature: Secp256k1Signature;
    }

    The arguments for signature verification.

    • aptosConfig: AptosConfig

      The configuration object for connecting to the Aptos network

    • message: HexInput

      The message that was signed.

    • signature: Secp256k1Signature

      The signature to verify, which must be an instance of Secp256k1Signature.

  Returns Promise<boolean>

  A boolean indicating whether the signature is valid for the given message.

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

Staticdeserialize

• deserialize(deserializer): Secp256k1PublicKey

• Parameters

  • deserializer: Deserializer

  Returns Secp256k1PublicKey
