Functions

func Parse

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

Parse parses a 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 that implements a sensible modular crypt interface.

password must be a plaintext password in UTF-8 format. salt must be a random salt value in binary form. N, r, and p are parameters for scrypt.

Returns a modular crypt hash.
