Types

type AESReader

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

Reader is an io.Reader that can read encrypted bytes. Now it only supports aes-128-cfb.

func NewAESReader

func NewAESReader(r io.Reader, key []byte) *AESReader

NewAESReader returns a new Reader that decrypts bytes from r

func (*AESReader) Read

func (r *AESReader) Read(p []byte) (nRet int, errRet error)

Read satisfies the io.Reader interface.

type AESWriter

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

Writer is an io.Writer that can write encrypted bytes. Now it only support aes-128-cfb.

func NewAESWriter

func NewAESWriter(w io.Writer, key []byte) (*AESWriter, error)

NewAESWriter returns a new Writer that encrypts bytes to w.

func (*AESWriter) Write

func (w *AESWriter) Write(p []byte) (nRet int, errRet error)

Write satisfies the io.Writer interface.

type WrappedConn

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

func (*WrappedConn) Close

func (rwc *WrappedConn) Close() error

func (*WrappedConn) Read

func (rwc *WrappedConn) Read(p []byte) (n int, err error)

func (*WrappedConn) Write

func (rwc *WrappedConn) Write(p []byte) (n int, err error)
