Challenge refusal

If the user rejects the challenge request, the PKSA can inform the HAS with the following message:

challenge_nack

{
    cmd: "challenge_nack",
    uuid: string,
    data: string,
    pok: string
}

Properties

• uuid: the challenge request identifier

• data: the uuid encrypted with auth_key and converted to Base64

• pok: the uuid encrypted using the account private key and the HAS server public key (see Proof of Key)
