Functions

func Decode

func Decode(chunks [][]byte) (data []byte, err error)

func Encode

func Encode(data []byte) (chunks [][]byte, err error)

Encode turns a byte slice into a set of shards with first byte containing the shard number. Previously this code included a CRC32 but this is unnecessary since the shards will be sent wrapped in HMAC protected encryption
