func HashFile

func HashFile(fn string) []byte

func HashImages

func HashImages(imageList []imageTypeList) []byte

func HashStrngOf

func HashStrngOf(data string) (h []byte)

HashStringOf calcualtes the hash of the 'data' and returns it.

func HashStrngOfReturnHex

func HashStrngOfReturnHex(data string) (s string)
