Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

func NewClient

func NewClient(mechs []gss.Mechanism) (c *Client, err error)

func (*Client) AcceptSecContext

func (c *Client) AcceptSecContext(buf []byte) (res []byte, err error)

AcceptSecContext should only be called by a server application

func (*Client) InitSecContext

func (c *Client) InitSecContext(inputToken []byte) (res []byte, err error)

func (*Client) SessionKey

func (c *Client) SessionKey() []byte

type KRB5Initiator

type KRB5Initiator struct {
	User     string
	Password string
	Hash     []byte
	AESKey   []byte
	Domain   string
	DCIP     string

	SPN string
	// contains filtered or unexported fields
}

func (*KRB5Initiator) AcceptSecContext

func (i *KRB5Initiator) AcceptSecContext(sc []byte) (res []byte, err error)

func (*KRB5Initiator) GetUsername

func (i *KRB5Initiator) GetUsername() string

func (*KRB5Initiator) InitSecContext

func (i *KRB5Initiator) InitSecContext(inputToken []byte) (res []byte, err error)

func (*KRB5Initiator) IsNullSession

func (i *KRB5Initiator) IsNullSession() bool

func (i *KRB5Initiator) SetClient(c *krb5ssp.Client) error

func (*KRB5Initiator) Sum

func (i *KRB5Initiator) Sum(bs []byte) []byte

type NTLMInitiator

type NTLMInitiator struct {
	User        string
	Password    string
	Hash        []byte
	Domain      string
	LocalUser   bool
	NullSession bool
	Workstation string
	TargetSPN   string
	// contains filtered or unexported fields
}

NTLMInitiator implements session setup through NTLMv2. It does not support NTLMv1. It is possible to use hash instead of password.
