滴水逆向——RVA与FOA相互转换

（开始这段别人总结的比较好，我就拿来用了）

1.RVA2FOA

即我们现在知道内存状态下的偏移，需要找到文件状态下的偏移。
步骤如下图：

step1：内存中的地址减去内存基址得到偏移，即RVA。
step2：循环遍历节表中各个节的信息，判断在哪个节中。（需要满足：内存偏移+节数据没对齐的大小>image_panyi>内存偏移）
step3:找出在哪个节后，减去该节在内存中的偏移（VirturalAddress）得到在该节中的相对偏移。
step4:上一步得到的该节的相对偏移+该节在文件中的偏移(PointToRawData)，即得到FOA
2.FOA2RVA

现在我们已经知道如何从内存中的偏移转化为文件中的偏移。现在是它的逆过程
step1:文件中的地址减去文件基址，得到在文件中的偏移，即FOA。
step2:循环遍历节表中各个节的信息，判断在哪个节中。（文件对齐+文件偏移>file_panyi>文件偏移）
step3:找出在哪个节后，减去该节在文件中的偏移（VirturalAddress）得到在该节中的相对偏移。
step4:上一步得到的该节的相对偏移+该节在内存中的偏移(VirtualAddress)，即得到RVA。
