	Salt       []byte           // default: DefaultSalt
	Iterations int              // 迭代次数,次数越多加密与解密所需时间越长, default: 2048
	KeySize    int              // 期望密文长度,支持16,24,32, default: 32
	Hash       func() hash.Hash // 加密所使用的hash函数, default: DefaultHash(sha256.New)

func New

func New(c net.Conn, cfg Config) *Conn

New 创建一个aes cfb加密码的连接,通过提供的配置使用pbkdf2生成key,依靠key和hash生成iv

func (*Conn) Read

func (sf *Conn) Read(p []byte) (int, error)

Read reads data from the connection.

func (*Conn) Write

func (sf *Conn) Write(p []byte) (int, error)

Write writes data to the connection.
