Functions

func Base64Bytes

func Base64Bytes(n int) string

Base64Bytes returns n cryptographically-random bytes encoded as standard base64 (with padding). Used for ss2022 keys, which xray expects as a base64-encoded key of a specific byte length per cipher.

func Num

func Num(n int) int

Num generates a random integer between 0 and n-1.

func NumLower

func NumLower(n int) string

NumLower generates a random string of length n containing digits and lowercase letters only.

func Seq

func Seq(n int) string

Seq generates a random string of length n containing alphanumeric characters (numbers, lowercase and uppercase letters).
