Functions ¶

func AnonymizedDNSHeader ¶

func AnonymizedDNSHeader() []byte

func CertMagic ¶

func CertMagic() []byte

these are the fingerprint of the dnscrypt protocols, keep in mind

func Query ¶

func Query(dialFn common.DialFn, proto string, service *Service, bin *[]byte, upstreamAddr, relayAddr *common.Endpoint) (*[]byte, error)

looks like a standard dns query via user-defined port, nevertheless it's fixed with fingerprints

func RetrieveServicesInfo ¶

func RetrieveServicesInfo(useSk bool, resolver *Resolver, dialFn common.DialFn, proto string, upstreamAddr *common.Endpoint, relays *[]*common.Endpoint) (time.Duration, error)

func ServerMagic ¶

func ServerMagic() []byte

Types ¶

type CryptoConstruction ¶

type CryptoConstruction uint8

const (
	UndefinedConstruction CryptoConstruction = iota
	XSalsa20Poly1305
	XChacha20Poly1305
)

type Resolver struct {
	Name        *string
	Identifiers []string

	V1_Services *atomic.Value //[]*ServiceInfo
	V2_Services *atomic.Value //[]*ServiceInfo
	VN_Services *atomic.Value //[]*ServiceInfo
}
