Functions ¶

func CheckCipherMethod ¶

func CheckCipherMethod(method string) error

func Pipe ¶

func Pipe(src io.Reader, dst io.Writer)

func Sort ¶

func Sort(arr []uint64, comparison func(uint64, uint64) int64) []uint64

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.

type Conn ¶

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

func NewConn ¶

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

func (*Conn) Close ¶

func (c *Conn) Close() error

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
)

type LeakyBuf ¶

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

func NewLeakyBuf ¶

func NewLeakyBuf(n, bufSize int) *LeakyBuf

NewLeakyBuf creates a leaky buffer which can hold at most n buffer, each with bufSize bytes.

func (*LeakyBuf) Get ¶

func (lb *LeakyBuf) Get() (b []byte)

Get returns a buffer from the leaky buffer or create a new buffer.

func (*LeakyBuf) Put ¶

func (lb *LeakyBuf) Put(b []byte)

Put add the buffer into the free buffer pool for reuse. Panic if the buffer size is not the same with the leaky buffer's. This is intended to expose error usage of leaky buffer.

type PacketConn ¶

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

func NewPacketConn ¶

func NewPacketConn(c net.PacketConn, cipher *Cipher) *PacketConn

func (*PacketConn) Close ¶

func (c *PacketConn) Close() error

func (*PacketConn) ReadFrom ¶

func (c *PacketConn) ReadFrom(b []byte) (n int, src net.Addr, err error)

func (*PacketConn) WriteTo ¶

func (c *PacketConn) WriteTo(b []byte, dst net.Addr) (n int, err error)

type PacketStreamConn ¶

type PacketStreamConn struct {
	net.Conn
}

func NewPacketStreamConn ¶

func NewPacketStreamConn(c net.Conn) *PacketStreamConn

func (*PacketStreamConn) Read ¶

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

func (*PacketStreamConn) Write ¶

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