Functions ¶
func AddRecordLayer ¶
AddRecordLayer adds record layer to data
func BtoInt ¶
BtoInt converts a byte slice into int in Big Endian order Uint methods from binary package can be used, but they are messy
func ComposeReply ¶
func ComposeReply(ch *ClientHello) []byte
ComposeReply composes the ServerHello, ChangeCipherSpec and Finished messages together with their respective record layers into one byte slice. The content of these messages are random and useless for this plugin
func IsSS ¶
func IsSS(input *ClientHello, sta *State) bool
IsSS checks if a ClientHello belongs to shadowsocks
func PeelRecordLayer ¶
PeelRecordLayer peels off the record layer
func PsudoRandBytes ¶
PsudoRandBytes returns a byte slice filled with psudorandom bytes generated by the seed
Types ¶
type ClientHello ¶
type ClientHello struct {
// contains filtered or unexported fields
}
ClientHello contains every field in a ClientHello message
func ParseClientHello ¶
func ParseClientHello(data []byte) (ret *ClientHello, err error)
ParseClientHello parses everything on top of the TLS layer (including the record layer) into ClientHello type
type State ¶
type State struct {
WebServerAddr string
Key string
AESKey []byte
Now func() time.Time
SS_LOCAL_HOST string
SS_LOCAL_PORT string
SS_REMOTE_HOST string
SS_REMOTE_PORT string
M sync.RWMutex
UsedRandom map[[32]byte]int
}
State type stores the global state of the program
func (*State) ParseConfig ¶
ParseConfig parses the config (either a path to json or in-line ssv config) into a State variable
func (*State) SetAESKey ¶
func (sta *State) SetAESKey()
SetAESKey calculates the SHA256 of the string key
func (*State) UsedRandomCleaner ¶
func (sta *State) UsedRandomCleaner()
UsedRandomCleaner clears the cache of used random fields every 12 hours
