hex - 检测 exe 32/64bit

Question

如何手动[没有任何额外的脚本/程序]查看 Windows 可执行文件是否为 32/64 位？

我一直在环顾四周，发现应该是我的答案。据我了解，在 60 字节处，下面的数字应该会出现。

I386 0x014c

IA64 0x0200

AMD64 0x8664

跳转到PE偏移后，还是没有看到机器类型。我做了一个查找并没有看到任何匹配项[除非由于某种原因它接近底部]。64 86 06 00 不在上面的列表中，所以我不知道我做错了什么。

    Notepad.exe (64bit)

Answer 1

出现的 60 字节不是机器类型，而是 PE 标头的偏移量。（在本例中，0x00000100：256 字节。）PE 标头开始：'P'、'E'、00、00。之后是机器类型。

Answer 2

OMG想通了。列出 AMD64 0x86 64 的代码匹配“64 86”。我从来没有意识到它被翻转了。
