(I downloaded a hashcalc tool, the Chinese version, but it has been modified, and I have to call soft2n.com Chinese description.exe. After looking at it, I found that the import table of hashcalc.exe has been modified, and put soft2n.com Chinese description.exe. It's in the import function. So when the program starts, if there is no such file, the program can't run. Use the tool to modify the import table. It's done, the principle is very simple.)
