Constants

const BlockSize = md4.BlockSize

The blocksize of eD2k in bytes.

const ChunkSize = 9728000

The chunk size of eD2k in bytes.

const Size = md4.Size

The size of an eD2k checksum in bytes.

Types

type Hash

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

A Hash is an implementation of hash.Hash for eD2k.

func New

func New() *Hash

New returns a new Hash computing the eD2k checksum.

func (*Hash) BlockSize

func (h *Hash) BlockSize() int

BlockSize returns the hash's underlying block size. The Write method must be able to accept any amount of data, but it may operate more efficiently if all writes are a multiple of the block size.

func (*Hash) Reset

func (h *Hash) Reset()

Reset resets the Hash to its initial state.

func (*Hash) Size

func (h *Hash) Size() int

Size returns the number of bytes Sum will return.

func (*Hash) Sum

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

Sum appends the current hash to b and returns the resulting slice. It does not change the underlying hash state.

func (*Hash) Write

func (h *Hash) Write(p []byte) (int, error)

Write adds more data to the running hash. It never returns an error.
