Enum AttestationKind 

#[non_exhaustive]
pub enum AttestationKind {
    HardwareCertChain,
    TpmQuote,
    Pkcs11Attributes,
}

The kind of attestation evidence a backend can produce.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HardwareCertChain

Vendor cert chain proving on-device generation. Independently verifiable against a public manufacturer root CA. Examples: YubiKey F9 attestation, Thales Luna PKC (Public Key Confirmation).

TpmQuote

TPM signed quote over PCR values with nonce. Proves platform state.

Pkcs11Attributes

PKCS#11 attribute flags: CKA_ALWAYS_SENSITIVE=true + CKA_NEVER_EXTRACTABLE=true. Trustworthy within the HSM’s trust boundary but not independently cryptographically verifiable.
