Types

type AuthData 

type AuthData struct {
	Password   string
	CookieData []byte
}

AuthData declares the data passed for authentication.

  • Password may be declared for AUTH_HASHEDPASSWORD authentication.
  • CookieData may be declared to pass a cookie-file's contents manually. If CookieData is nil, AUTH_COOKIE and AUTH_SAFECOOKIE authentication will read the first available cookie-file's contents automatically.

type AuthMethod 

type AuthMethod string

AuthMethod declares the way of authentication on the ControlPort connection. 

const (
	// AUTH_NULL No authentication is required.
	//
	// To prevent cross-protocol attacks, calling authenticate is still required, even when all methods are disabled.
	AUTH_NULL AuthMethod = "NULL"
	// AUTH_HASHEDPASSWORD A password needs to be presented.
	//
	// The password's hash is defined in the configuration.
	AUTH_HASHEDPASSWORD AuthMethod = "HASHEDPASSWORD"
	// AUTH_COOKIE A cookie-file's contents must be provided.
	//
	// The Controller needs to prove its privileges to read one of them.
	AUTH_COOKIE AuthMethod = "COOKIE"
	// AUTH_SAFECOOKIE A Challenge must be completed
	//
	// The Controller needs to prove its knowledge of a cookie-file, similar to AUTH_COOKIE.
	AUTH_SAFECOOKIE AuthMethod = "SAFECOOKIE"
)

type Cmd 

type Cmd string

Cmd represents a direct command on the ControlPort protocol

Usage of Cmd outside the module itself will be mostly obsolete once all commands are implemented on the LowController API.

	CMD_SETCONF                  Cmd = "SETCONF"

type Controller 

type Controller struct {
	TorVersion    string
	TorRCPath     string
	VersionStatus string
	LowController *LowController
	// contains filtered or unexported fields
}

Controller provides a high-level API for communication over TOR's ControlPort protocol.

Certain functions may declare high concurrency-safety.

func NewController 

func NewController() *Controller

func (*Controller) Authenticate 

func (c *Controller) Authenticate(method AuthMethod, data AuthData) error

Authenticate the connection using the given AuthMethod and (if required) AuthData

This function is fully thread-safe, although there shouldn't be any scenario, where that's applicable

func (*Controller) HSDescAvailable 

func (c *Controller) HSDescAvailable(addr string) (bool, error)

HSDescAvailable checks for the availability of the given hidden service on the hash-ring. This usually means, that the hidden service is reachable.

This function is fully thread-safe

func (*Controller) NewIdentity 

func (c *Controller) NewIdentity() error

NewIdentity switches to new circuits, so that new requests don't share any circuits with old ones.

This function is fully thread-safe, although TOR might rate-limit its usage.

func (*Controller) Open 

func (c *Controller) Open(addr string) error

func (*Controller) RegisterEvent 

func (c *Controller) RegisterEvent(code EventCode, callback func([]ReplyLine)) error

RegisterEvent sets the callback function for the given event.

This function is fully thread-safe.

func (*Controller) UnregisterEvent 

func (c *Controller) UnregisterEvent(code EventCode) error

UnregisterEvent removes the set callback function for the given event.

This function is fully thread-safe.
