Example #1

func (g *generator) Sum256Number(data []byte) int64 {
	var result [8]uint32

	C.asm_sha256_hash((*C.uint8_t)(&data[0]),
		C.uint32_t(len(data)),
		(*C.uint32_t)(&result[0]))

	return int64(result[7]) + ((int64(result[6]) & 0x0000ffff) << 0x20)
}

Example #2

func (g *generator) Sum256NumberCmp(data []byte, work int64) bool {
	var result [8]uint32

	C.asm_sha256_hash((*C.uint8_t)(&data[0]),
		C.uint32_t(len(data)),
		(*C.uint32_t)(&result[0]))

	value := int64(result[7])
	if value > work {
		return false
	}

	value += ((int64(result[6]) & 0x0000ffff) << 0x20)
