Functions

func CreateDerivedKey

func CreateDerivedKey(password string) (_ string, err error)

CreateDerivedKey creates an encoded derived key with a random hash for the password.

func IsDerivedKey

func IsDerivedKey(s string) bool

func ParseDerivedKey

func ParseDerivedKey(encoded string) (dk, salt []byte, time, memory uint32, threads uint8, err error)

ParseDerivedKey returns the parts of the encoded derived key string.

func VerifyDerivedKey

func VerifyDerivedKey(dk, password string) (_ bool, err error)

VerifyDerivedKey checks that the submitted password matches the derived key.

func Strength

func Strength(password string) PasswordStrength

Strength is currently a very simple password strength algorithm that simply checks the length and contents of a password to ensure that reasonable passwords are added to Quarterdeck. In the future this algorithm can be strengthened with zxcvbn algorithms. TODO: implement dictionary word, spatial closeness, and l33t strength algorithms.
