Functions

func New256

func New256(key []byte) (hash.Hash, error)

New256 returns a new hash.Hash computing the BLAKE2b-256 checksum. A non-nil key turns the hash into a MAC. The key must between zero and 64 bytes long.

func New384

func New384(key []byte) (hash.Hash, error)

New384 returns a new hash.Hash computing the BLAKE2b-384 checksum. A non-nil key turns the hash into a MAC. The key must between zero and 64 bytes long.

func New512

func New512(key []byte) (hash.Hash, error)

New512 returns a new hash.Hash computing the BLAKE2b-512 checksum. A non-nil key turns the hash into a MAC. The key must between zero and 64 bytes long.

func Sum256

func Sum256(data []byte) [Size256]byte

Sum256 returns the BLAKE2b-256 checksum of the data.

func Sum384

func Sum384(data []byte) [Size384]byte

Sum384 returns the BLAKE2b-384 checksum of the data.

func Sum512

func Sum512(data []byte) [Size]byte

Sum512 returns the BLAKE2b-512 checksum of the data.
