Hash verification tool

There are so many Hash tools. I wrote this out of boredom and shared it with friends in need.

Function introduction

1. Only supports commonly used MD5, SHA1, and CRC32 algorithms;
2. Support drag-and-drop operations for multiple files or folders;
3. Support parameter startup (the parameter is one or more file or folder paths);
4. Supports saving personal settings (saved in the registry by default, if an ini file with the same name exists, it will be saved in the ini file);
5. Support hash value comparison (actually a string search function);
6. Support stopping and restarting calculation operations;
7. Support Windows 7 taskbar progress bar effect;

Change log

1. Added "right-click menu", "send menu", and "window on top" (right-click the mouse title bar and select from the pop-up menu)

2. Modify the effect of displaying file size. Every three digits are separated by commas, which is consistent with the Windows system display.

3. Modify the logic of calculating files multiple times (the previous version only calculated the last selected file, now it waits for the previous calculation to complete before calculating subsequent added files)
