Constants

const RecommendedN = 16384

The current recommended N value for interactive logins.

const Recommendedp = 1

The current recommended p value for interactive logins.

const Recommendedr = 8

The current recommended r value for interactive logins.

Variables

var ErrInvalidStub = fmt.Errorf("invalid scrypt password stub")

Indicates that a password hash or stub is invalid.

Functions

func Parse

func Parse(stub string) (salt, hash []byte, N, r, p int, err error)

Parses an scrypt modular hash or stub string.

The format is as follows:

$s2$N$r$p$salt$hash    // hash
$s2$N$r$p$salt         // stub

func ScryptSHA256

func ScryptSHA256(password string, salt []byte, N, r, p int) string

Wrapper for golang.org/x/crypto/scrypt implementing a sensible modular crypt interface.

password should be a UTF-8 plaintext password. salt should be a random salt value in binary form.

N, r and p are parameters to scrypt.

Returns a modular crypt hash.
