Functions

func CalcPadding

func CalcPadding(length, blkSize int) int

CalcPadding returns the number of padding bytes needed to round length bytes to a multiple of blkSize

func Checksum

func Checksum(srcs ...common.RawBytes) uint16

Calculate RFC1071 checksum of supplied data chunks. If a chunk has an odd length, it is padded with a 0 during checksum computation.

func FillPadding

func FillPadding(b common.RawBytes, length, blkSize int) int

func InitMac

func InitMac(key common.RawBytes) (hash.Hash, error)

func Mac

func Mac(mac hash.Hash, msg common.RawBytes) (common.RawBytes, error)

func TimeToString

func TimeToString(t uint64) string

func UDPAddrEqual

func UDPAddrEqual(a, b *net.UDPAddr) bool

Types

type ASList

type ASList struct {
	Core    []*addr.ISD_AS
	NonCore []*addr.ISD_AS

func LoadASList

func LoadASList(fileName string) (*ASList, error)

LoadASList parses the yaml file fileName and returns a structure with non-core and core ASes.

type B64Bytes

}

func (*Raw) Peek

func (r *Raw) Peek(p []byte) (int, error)

func (*Raw) Read

func (r *Raw) Read(p []byte) (int, error)

func (*Raw) Write

func (r *Raw) Write(p []byte) (int, error)
