public async ByteArray? challenge (ByteArray? token, int io_priority, Cancellable? cancellable = null) throws Error
If token is null, asynchronously generate the initial SASL message to send to the server.
(This will be null if the client doesn't initiate the exchange.) Otherwise, token is a
challenge from the server, and the asynchronous result is the response.
When the operation is finished, callback will be called. You can then call challenge.end to get
the result of the operation.
