CredentialRequest
A credential request, created by the client, to be sent to the server.
This declaration is deprecated: ARC(P-384) has been removed from the IETF draft; use ARC(P-256) instead.
struct CredentialRequestClients should not create values of this type manually; they should use the prepare method on the public key.
Servers should reconstruct values of this type from the serialized bytes sent by the client.
