Struct AuthenticatorData

pub struct AuthenticatorData {
    pub rp_id_hash: [u8; 32],
    pub flags: AuthenticatorFlags,
    pub sign_count: u32,
    pub attested_credential_data: Option<AttestedCredentialData>,
    pub extensions: Option<HashMap<String, Value>>,
    pub raw: Vec<u8>,
}

Expand description

Fully parsed authenticator data.

Fields§

§rp_id_hash: [u8; 32]

SHA-256 hash of the RP ID. Verified against SHA-256(rp_id) by the caller.

§flags: AuthenticatorFlags

Decoded flags byte.

§sign_count: u32

Authenticator-maintained signature counter.

§attested_credential_data: Option<AttestedCredentialData>

Present only during registration (when the AT flag is set).

§extensions: Option<HashMap<String, Value>>

Extension data from the authenticator (§6.1 / §10.5), present when the ED flag is set.

Keys are extension identifiers (e.g. "credProps", "appid"); values are raw CBOR. Unknown extensions are stored as-is — the library never rejects an unrecognised key.

§raw: Vec<u8>

The original raw bytes of this authenticator data structure.

Kept because the signed payload for authentication is authData || SHA-256(clientDataJSON) — the exact bytes matter.
