Public Member Functions
	AuthenticationKey (byte[] bytes)
	Initialize the Authentication Key.
string	DerivedAddress ()
	Derives hexadecimal Address from authentication key array of bytes.

Static Public Member Functions
static AuthenticationKey	FromMultiEd25519PublicKey (MultiEd25519PublicKey publicKey)
	Converts a K-of-N MultiEd25519PublicKey to AuthenticationKey with: auth_key = sha3-256(p_1 | � | p_n | K | 0x01). K represents the K-of-N required for authenticating the transaction. 0x01 is the 1-byte scheme for multisig. .
static AuthenticationKey	FromEd25519PublicKey (byte[] publicKey)
	Converts single Public Key (bytes) into Authentication Key auth_key = sha3-256(pubkey_A | 0x00) where | denotes concatenation. The 0x00 is the 1-byte single-signature scheme identifier. .

Public Attributes
byte[]	bytes
	Byte array representing authentication key.

Static Public Attributes
static int	LENGTH = 32
	Byte length of authentication key.

Detailed Description

Represents an Authentication Key
During the account creation process, a 32-byte authentication key comes to exist first.
This authentication key is then returned as it is as the 32-byte account Address.
.

NOTE: Generating the authentication key for an account requires that you provide one of
the below 1-byte signature scheme identifiers for this account, i.e.,
whether the account is a single signature or a multisig account:

Constructor & Destructor Documentation

AuthenticationKey()

Aptos.Accounts.AuthenticationKey.AuthenticationKey ( byte[]  bytes )

inline

Initialize the Authentication Key.

Parameters

bytes

The raw byte array of the key itself.

Exceptions

ArgumentException

Member Function Documentation

DerivedAddress()

string Aptos.Accounts.AuthenticationKey.DerivedAddress ( )

inline

Derives hexadecimal Address from authentication key array of bytes.

Returns

A hexa string representation Address of the authentication key

FromEd25519PublicKey()

static AuthenticationKey Aptos.Accounts.AuthenticationKey.FromEd25519PublicKey ( byte[]  publicKey )

inlinestatic

Converts single Public Key (bytes) into Authentication Key
auth_key = sha3-256(pubkey_A | 0x00)
where | denotes concatenation. The 0x00 is the 1-byte single-signature scheme identifier.
.

Parameters

publicKey

Publick key, in byte array format, used to generate the authentication key

Returns

Authentication key object

FromMultiEd25519PublicKey()

static AuthenticationKey Aptos.Accounts.AuthenticationKey.FromMultiEd25519PublicKey ( MultiEd25519PublicKey  publicKey )

inlinestatic

Converts a K-of-N MultiEd25519PublicKey to AuthenticationKey with:
auth_key = sha3-256(p_1 | � | p_n | K | 0x01). K represents the K-of-N required for
authenticating the transaction. 0x01 is the 1-byte scheme for multisig.
.

Returns

Authentication key object from a multi ED25519 key
