Functions

func CheckCipherMethod

func CheckCipherMethod(method string) error

func GetRequest

func GetRequest(conn *Conn) (host string, err error)

func RawAddr

func RawAddr(addr string) (buf []byte, err error)

Types

type Cipher

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

func NewCipher

func NewCipher(method, password string) (c *Cipher, err error)

NewCipher creates a cipher that can be used in Dial() etc. Use cipher.Copy() to create a new cipher with the same method and password to avoid the cost of repeated cipher initialization.

func (*Cipher) Copy

func (c *Cipher) Copy() *Cipher

Copy creates a new cipher at it's initial state.

func (*Cipher) Decrypt

func (c *Cipher) Decrypt(src []byte) (data []byte)

func (*Cipher) Encrypt

func (c *Cipher) Encrypt(src []byte) (cipherData []byte)

type Conn

type Conn struct {
	net.Conn
	*Cipher
	// contains filtered or unexported fields
}

func Dial

func Dial(addr, server string, cipher *Cipher) (c *Conn, err error)

addr should be in the form of host:port

func DialWithRawAddr

func DialWithRawAddr(rawConn *net.Conn, rawaddr []byte, server string, cipher *Cipher) (c *Conn, err error)

This is intended for use by users implementing a local socks proxy. rawaddr shoud contain part of the data in socks request, starting from the ATYP field. (Refer to rfc1928 for more information.)

func NewConn

func NewConn(c net.Conn, cipher *Cipher) *Conn

func (*Conn) Close

func (c *Conn) Close() error

func (*Conn) GetAndIncrChunkId

func (c *Conn) GetAndIncrChunkId() (chunkId uint32)

func (*Conn) GetIv

func (c *Conn) GetIv() (iv []byte)

func (*Conn) GetKey

func (c *Conn) GetKey() (key []byte)

func (*Conn) IsOta

func (c *Conn) IsOta() bool

func (*Conn) Read

func (c *Conn) Read(b []byte) (n int, err error)

func (*Conn) Write

func (c *Conn) Write(b []byte) (n int, err error)

type DecOrEnc

type DecOrEnc int

const (
	Decrypt DecOrEnc = iota
	Encrypt
)
