Functions

func Zero

func Zero(h Hash)

Zero copies a cleanly initialised empty slice over top of the provided Hash.

Types

type Hash

type Hash [32]byte

Hash is just a 256-bit hash.

func Double

func Double(b []byte) Hash

Double runs a standard double SHA256 hash and does all the slicing for you.

func New

func New() Hash

New creates a correctly sized slice for a Hash.

func Single

func Single(b []byte) Hash

Single runs a standard SHA256 hash.

func (Hash) Based32String

func (h Hash) Based32String() string

Based32String returns the Basde32 encoded form of a SHA256 hash.

func (Hash) String

func (h Hash) String() string

String returns the hex encoded form of a SHA256 hash.

func (Hash) Zero

func (h Hash) Zero()

Zero out the values in the hash. Hashes can be used as secrets.
