The key_id is the subject key for which an attestation certificate is created, and theattestation_key_id will be used to sign the attestation certificate.

If no attestation key is given, the device’s default attestation key will be used, and can be verified against Yubico’s certificate.

Security Warning

This is a low-level ECDSA API, and if used incorrectly could potentially result in forgeable signatures.

We recommend using the [ecdsa::Signer] type instead, which provides a high-level, well-typed, misuse resistant API.
