1.1.4 IP地址表示: C网络程序使用structsockaddr来表示IP地址,是二进制,而不是python中常见的二进制。IPv4在python和c之间的切换使用inet_aton()和inet_ntoa()。 socket.inet_aton(ip_string) 把字符串格式的ip地址转换为 c语言格式,比如‘192.168.1.1’->c0a80101。支持IPV6需要使用inet_pton。 socket.inet_n...
Pwntools的目标是以半标准的方式提供所有这些,这样你就可以停止复制粘贴相同的struct.unpack('>I', x)代码,而是使用更多稍微清晰的包装器,如pack或p32甚至p64(..., endian='big', sign=True)。 除了对日常的功能进行方便的包装外,它还提供了一套非常丰富的IO管道,将所有你曾经执行过的IO封装在一个统一的界面...
