MD5Digest Calculator

MD5Digest Calculator tool was developed to be a C++ MFC application that calculates MD5 digest of files, using worker threads. The MD5 calculator C++ class can be used also in non-MFC projects.

This is a C++ MFC application that computes the MD5 digest of files, using worker threads. The input file can be selected from the app main dialog box, or it can be drag-and-drop'ed by the user.

The MD5 computation is done by a "background" worker thread. (See CMfcMD5CalculatorDlg::MD5WorkerThreadFunctionMain() method.)

MD5 digest can be copied to the clipboard. Some techniques showed in this project: - MD5 calculation using Win32 Cryptography API (no external libraries required) - using worker threads - drag-and-drop - copy strings to clipboard - extracting file path and file title from full file pathname - using common open file dialog

The CMD5FileCalculator class is used to calculate MD5 digest of files. I designed this class to be independent from the MFC framework, so this class can be used also in other C++ non-MFC projects.
