func (*FakeHasher) BatchHash

func (f *FakeHasher) BatchHash(msg [][]byte) (hash []byte, err error)

BatchHash hash with two-dimensional array

func (*FakeHasher) BlockSize

func (f *FakeHasher) BlockSize() int

BlockSize hash block size

func (*FakeHasher) Hash

func (f *FakeHasher) Hash(msg []byte) (hash []byte, err error)

Hash compute hash

func (*FakeHasher) Reset

func (f *FakeHasher) Reset()

Reset reset state

func (*FakeHasher) Size

func (f *FakeHasher) Size() int

func (*FakeHasher) Sum

func (f *FakeHasher) Sum(b []byte) []byte

Sum hash sum

func (*FakeHasher) Write

func (f *FakeHasher) Write(p []byte) (n int, err error)

Write write data

type HashType

type HashType uint32

HashType represent hash algorithm type

type Hasher

type Hasher struct {
	// contains filtered or unexported fields
}

Hasher thw return value of function NewHasher

func NewHasher

func NewHasher(hashType HashType) *Hasher

NewHasher instruct a Hasher, the incoming parameter is the algorithm type.

func (*Hasher) BatchHash

func (h *Hasher) BatchHash(msg [][]byte) (hash []byte, err error)

BatchHash hash with two-dimensional array

func (*Hasher) BlockSize

func (h *Hasher) BlockSize() int

BlockSize hash block size

func (*Hasher) Hash

func (h *Hasher) Hash(msg []byte) (hash []byte, err error)

Hash compute hash

func (*Hasher) HashBuffer

func (h *Hasher) HashBuffer(msg []byte, buf []byte) (hash []byte, err error)

HashBuffer is identical to Hash except that it stages through the provided buffer (if one is required) rather than allocating a temporary one. If buf is nil or has un-expected size, one fix-sized bytes will be allocated.

func (*Hasher) Reset

func (h *Hasher) Reset()

Reset reset state

func (*Hasher) Size

func (h *Hasher) Size() int

Size hash size

func (*Hasher) Sum

func (h *Hasher) Sum(b []byte) []byte
