func ByteToBits(x byte) (ret [8]byte)

ByteToBits convert a byte into a slice of bits

func CheckLastByteEqual(respByte, serverComputing []byte, diff uint16) bool

func ConcatIDAndTestSolution(id, try []byte) []byte

ConcatIDAndTestSolution make a string containing the challenge ID and the try. It make the try unique for any challenge

func EqualByte(b1, b2 byte, diff uint16) bool

EqualByte is supposed to be called on the last byte of the check

func GetDiffAsByte(diff uint16) uint

GetDiffAsByte returns the numbers of bytes needed to hold the this numbers of bits.

func Hash(t *TryStruct) ([]byte, error)

Hash do the hash function

func IDToSlice(id uint64) []byte

IDToSlice is a simple function witch get an integer and return a slice of bytes.

func Try(t *TryStruct, tryChan chan *TryResponse)

Try try the given solution and return the result into the given channel

type TryResponse struct {
	Found    bool   // Been found
	Solution []byte // Save the solution
}

TryResponse represent the response of the try.

type TryStruct struct {
	N, Salt, Target []byte
	ResponseChan    chan *TryResponse

	Challenge *request.Challenge
}

TryStruct is a struct used to define what paramiters must be used for this try.
