3.大文件划块计算哈希值：

with open(listA[i], 'rb', buffering=0) as f:  # 二进制读取文件
            print(i)
            sha224 = hashlib.sha224()  # 哈希 sha224
            while True:
                IV00 = f.read(8192)  # 一次读取8192，分段读取，直至读取完毕
                sha224.update(IV00)  # 拼接
                # print(IV00)
                if not IV00:
                    break
        # print(sha224.hexdigest())
        listB.append(sha224.hexdigest())  # 将sha224哈希值写入listB
        progressbarOne['value'] += 1  # 进度值+1
