Retrieve a Challenge

POST /challenge

Request body:

{"pubkey": [0, 0]

(Serialized as byte array)

Response:

{
    "challenge": [1, 2, 3],
    "state": [4, 5, 6],
    "nonce": [7, 8, 9]
}

Keep state and nonce, you need to send them in the response. Decrypt challenge with your private key, this will give you a plaintext (the challenge response).
