Functions

func Sign

func Sign(salt []byte, id, pass string, args ...int) (checkPass string)

Sign generates a string checkPass with PBKDF2 & SHA-3 by the user' id and pass. http://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-132.pdf recommended salt length >= 16 bytes default iter count is 12480 default result length is 64

fmt.Println(Sign([]byte("salt..."), "user_id", "user_password"))
fmt.Println(Sign([]byte("salt..."), "user_id", "user_password"), 1024) // iterCount == 1024
fmt.Println(Sign([]byte("salt..."), "user_id", "user_password"), 1024, 32)

func Verify

func Verify(salt []byte, id, pass, checkPass string, args ...int) bool

Verify verify user' id and password that generated by Sign

fmt.Println(Verify([]byte("salt..."), "user_id", "user_password", checkPass))

Types
