Package-level declarations

Types

AccountPublicKey

abstract class AccountPublicKey : PublicKey

An abstract representation of an account public key.

AnyPublicKey

class AnyPublicKey(val publicKey: PublicKey) : AccountPublicKey

Represents any public key supported by Aptos.

AnySignature

class AnySignature(val signature: Signature) : Signature

Instance of signature that uses the SingleKey authentication scheme. This signature can only be generated by a SingleKeySigner, since it uses the same authentication scheme.

Ed25519PrivateKey

class Ed25519PrivateKey(data: HexInput) : PrivateKey

Represents the private key of an Ed25519 key pair.

Ed25519PublicKey

@Serializable

class Ed25519PublicKey(data: ByteArray) : AccountPublicKey

Represents the public key of an Ed25519 key pair.

Ed25519Signature

@Serializable

class Ed25519Signature(hexInput: ByteArray) : Signature

A signature of a message signed using an Ed25519 private key

KeyPair

data class KeyPair(val privateKey: ByteArray, val publicKey: ByteArray)

Represents a pair of signing keys: a public key and a private key.

PrivateKey

interface PrivateKey

An interface of a private key. It is associated to a signature scheme and provides signing capabilities.

PublicKey

abstract class PublicKey

An abstract representation of a public key.

Secp256k1PrivateKey

class Secp256k1PrivateKey(hexInput: HexInput) : PrivateKey

A Secp256k1 ecdsa private key

Secp256k1PublicKey

class Secp256k1PublicKey(hexInput: HexInput) : PublicKey

Represents the Secp256k1 ecdsa public key

Secp256k1Signature

class Secp256k1Signature(hexInput: HexInput) : Signature

Signature

abstract class Signature

An abstract representation of a crypto signature, associated to a specific signature scheme e.g. Ed25519 or Secp256k1

VerifySignatureArgs

data class VerifySignatureArgs(val message: HexInput, val signature: Signature)
