func MakeCodebook

func MakeCodebook(codeset, mask string) string

func Power2

func Power2(n int64) int64

Power2 returns the max exponent x where 2^x < n!

func RandomBytes

func RandomBytes(size int) ([]byte, error)

func S2b

func S2b(s string) []byte

func SPA

func SPA(secret, salt []byte, keyLen, iteration int) ([]byte, error)

func SPAKDF

func SPAKDF(raw, salt []byte, keyCount, keyLen, iteration int) ([][]byte, error)

func SPIHash

func SPIHash(secret, key []byte) []byte

func SPIKey

func SPIKey(secret, key, newSecret []byte) []byte

SPIKey returns a new key for the new secret given the old secret and key, the new secret and key will hash to the same value with hmac/fnv. The old key is divided into chunks of 3 bytes and used for the computation of the new key based on hmac/fnv hash.

func SpaceOut

func SpaceOut(s string, divisor int) string

SpaceOut inserts spaces.
