有些代码每个人都写过无数次,而且每个人都有自己的方法。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)。

The dict API is marginally slower than the traditional one. As the packing/unpacking performance is quite high, the overhead of performing dictionary lookups and hashing significantly increas pack and unpacking duration.AboutFaster C implementation of the bitstruct Python library Topics...
