Functions

func ParsePassword

func ParsePassword(passwordString string) (*password, error)

解析采用base64编码的字符串获取密码

func RandPassword

func RandPassword() string

产生 256个byte随机组合的 密码，最后会使用base64编码为字符串存储在配置文件中 不能出现任何一个重复的byte位，必须又 0-255 组成，并且都需要包含

func WrapConn

func WrapConn(rawConn net.Conn, cipher *Cipher) (net.Conn, error)

see net.DialTCP

func WrapListener

func WrapListener(lis net.Listener, cipher *Cipher) net.Listener
