代码解释：
randBytes = [bytes_to_long(os.urandom(64)) for _ in range(3)]
"""
这段代码是用Python来生成一个包含3个随机64字节长的bytes对象的列表。让我逐步解释：
os.urandom(64)：os.urandom()函数是Python中用于生成指定长度的随机字节序列的方法。在这里，os.urandom(64)生成了一个长度为64字节的随机字节序列。
bytes_to_long()：这是一个自定义的函数，它将一个字节序列转换为一个长整型数。在Python中，可以使用int.from_bytes()方法来实现这一转换。
[bytes_to_long(os.urandom(64)) for _ in range(3)]：这是一个列表推导式（list comprehension），它会生成一个包含3个元素的列表。在这里，循环了3次（range(3)），每次生成一个64字节长的随机字节序列，并将其转换为长整型数后加入到列表中。
因此，randBytes列表包含了3个随机的64字节长的长整型数。

代码解释不懂，不用管，直接解。
