func InsecurePasswordHash ¶

func InsecurePasswordHash(password, salt []byte, m, t, n uint) []byte

InsecurePasswordHash calculates a CPU- and memory-hard hash of the given password and salt. It takes two exponential parameters, M and T, which determine the memory and CPU costs. It also takes the length of the hash in bytes.

N.B.: THIS IS A TOTALLY EXPERIMENTAL ALGORITHM WHICH I WROTE BEFORE I'D HAD ANY COFFEE. DO NOT USE HACKY ALGORITHMS DESIGNED BY UNCAFFEINATED NON-CRYPTOGRAPHERS.

func NewHash ¶

func NewHash(size int) hash.Hash

NewHash returns a new instance of the Spritz hash with the given output size.

func NewMAC ¶

func NewMAC(key []byte, size int) hash.Hash

NewMAC returns a new instance of the Spritz MAC with the given key and output size.

func NewStream ¶

func NewStream(key []byte) cipher.Stream

NewStream returns a new instance of the Spritz cipher using the given key.

func NewStreamWithIV ¶

func NewStreamWithIV(key, iv []byte) cipher.Stream

NewStreamWithIV returns a new instance of the Spritz cipher using the given key and initialization vector.
