AuthenticatorPublicKey Property

AuthenticatorPublicKey

The public key returned by the YubiKey.

C#

public CoseKey? AuthenticatorPublicKey { get; protected set; }

Property Value

Type	Description
CoseKey

Remarks

The caller will obtain the YubiKey's public key using the GetKeyAgreementCommand and pass it to the Encapsulate(CoseKey) method. A reference to the key passed into that method will be stored in this property.

A call to Initialize() will set this to null. That is, a new public key must be obtained for each PIN/UV authentication session with the YubiKey. Even if the new session is initiated with the previously-used YubiKey, the public key must be obtained, because the YubiKey might generate a new public key.
