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 raw: Vec<u8>,
}

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).

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.
