Variables

var ErrCipherNotSupported = errors.New("cipher not supported")

ErrCipherNotSupported occurs when a cipher is not supported (likely because of security concerns).

Functions

func Kdf

func Kdf(password string, keyLen int) []byte

key-derivation function from original Shadowsocks

func ListCipher

func ListCipher() []string

ListCipher returns a list of available cipher names sorted alphabetically.
