Functions

func New

func New() hash.Hash

New returns a new sha256 hash.Hash if the returned hash is empty, then make a call to sslerr.Error()

func New224

func New224() hash.Hash

func Sum224

func Sum224(data []byte) (sum224 [Size224]byte)

Sum224 returns the SHA224 checksum of the data.

func Sum256

func Sum256(data []byte) (sum256 [Size]byte)

Sum256 returns the SHA256 checksum of the data.
