Struct WebAuthnAccount 

pub struct WebAuthnAccount { /* private fields */ }

Available on crate feature secp256r1 only.

A WebAuthn / Passkey-style account.

Wraps a Secp256r1PrivateKey but produces transaction signatures in the on-chain AnySignature::WebAuthn format. See the module-level docs for the precise wire format.

Implementations

impl WebAuthnAccount

pub fn generate() -> Self

Generates a new random WebAuthn account using the default RP-ID and origin (see DEFAULT_WEBAUTHN_RP_ID / DEFAULT_WEBAUTHN_ORIGIN).

pub fn from_private_key(private_key: Secp256r1PrivateKey) -> Self

Creates a WebAuthn account from an existing P-256 private key, using the default RP-ID and origin.

pub fn from_parts( private_key: Secp256r1PrivateKey, rp_id: &str, origin: &str, ) -> Self

Creates a WebAuthn account from a private key and explicit RP-ID / origin strings.

The on-chain verifier does not enforce particular values for these fields, but if you are interoperating with a relying party that records the rpIdHash / origin for off-chain auditing you may wish to specify them.

pub fn from_private_key_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates a WebAuthn account from private-key bytes.

Errors

Returns an error if bytes is not a valid 32-byte P-256 scalar.

pub fn address(&self) -> AccountAddress

Returns the account address (the on-chain authentication key).

pub fn public_key(&self) -> &Secp256r1PublicKey

Returns the underlying P-256 public key.

pub fn private_key(&self) -> &Secp256r1PrivateKey

Returns a reference to the underlying P-256 private key.
