func BuildURL(parts ...string) (string, error)

BuildURL constructs a URL from parts. It handles any irregularities like missing or extra slashes.

func PublicIP

func PublicIP(ipversion uint) (net.IP, error)

If a nil error is returned, the returned IP must be valid.

func Random32

func Random32() [32]byte

func RandomBytes

func RandomBytes(n int) []byte

func RandomHex

func RandomHex(n int) string

func RandomInt

func RandomInt(min, max int) int

func TrimHex

func TrimHex(s string) string
