Functions

func Password

func Password(bits int) (password string, err error)

Password creates a crypto strong password which is just about memorable. The password is composed of printable ASCII characters from the base64 alphabet.

Requires password strength in bits. 64 is just about memorable 128 is secure

func Seed

func Seed() error

Seed the global math/rand with crypto strong data

This doesn't make it OK to use math/rand in crypto sensitive environments - don't do that! However it does help to mitigate the problem if that happens accidentally. This would have helped with CVE-2020-28924 - #4783

func String

func String(n int) string

String create a random string for test purposes.

Do not use these for passwords.

func StringFn

func StringFn(n int, randIntn func(n int) int) string
