Functions

func Bytes

func Bytes(n int) ([]byte, error)

Bytes will help us generate n random bytes, or will return an error if there was one. This uses the crypto/rand package so it is safe to use with things like remember tokens.

func NBytes

func NBytes(base64String string) (int, error)

NBytes returns the number of bytes used in the base64 URL encoded string

func RememberToken

func RememberToken() (string, error)

RememberToken is a helper function designed to generate remember tokens of a predetermined byte size.

func String

func String(nBytes int) (string, error)

String will generate a byte slice of size nBytes and then return a string that is the base64 URL encoded version of that byte slice.
