calchash.exe和chckhash.exe计算pe文件hash值的两个实用小工具

第一部分：
C:\WINDOWS\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\NT5.CAT t部分内容

B B D 0 2 2 2 1 A A 6 5 5 6 2 8 F 4 9 5 F 6 C D 3 0 3 9 0 8 B B E 0 0 F 9 5 9 5  

第二部分：
D:\>calchash.exe pidgen.dll
BB D0 22 21 AA 65 56 28 F4 95 F6 CD 30 39 08 BB E0 0F 95 95

第三部分：
D:\>chckhash.exe pidgen.dll
C:\WINDOWS\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\NT5.CAT contains pidgen.dll
C:\WINDOWS\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\SP3.CAT contains pidgen.dll

第四部分：main函数主要调用了一个CryptCATAdminCalcHashFromFileHandle函数
