The Simple Qt File Hashing Application is an application that allows you to quickly and easily hash hundreds or more files utilizing the full power of your PC's processor cores. This application was designed from the start to be multi-threaded, supports dark mode, and has dozens of hash functions to choose from.

This application was initially designed as a weekend project, but became much larger than that as a single weekend was not sufficient to make this application presentable. Actually, even a month is cutting it close with this application, as the scope was considerably larger, but I prefer utilizing my skills on larger, more advanced projects anyway. The project's main GitHub repository is available here, and it should be where the most recent release can be found as well. Releases are not provided on KirHut.com due to bandwidth constraints.

NOTE: This application uses a custom MD5 implementation written in C++17. You should never count on MD5 for security or collision resistance in the first place, but moreover, do not rely on this implementation of MD5 to be 100% correct or resistant to side-channel attacks. Please report any inconsistency in the MD5 output as a bug for this project. All other hash functions are implemented by 3rd party libraries, namely Crypto++, but also for MD6 support this project uses the reference implementation published by Ron Rivest.

You should be able to open the application and select files to hash by using either the Select Files… button or the Select Directory… button. You may also drag and drop files into the application and that will work just as well. The algorithm that will be used to hash the files is under the drop-down menu labeled “Hashing Algorithm.” You may change this at any time to use a different hashing function.

You can use the Matching Window found under the Matching menu on the main window or, after you have completed a set of hashes, by pressing the Compare Hashes! button. The Matching Window allows you to quickly compare hashes to files that are hashed on the main hashing window.

There's some features that are not complete:

• The Context Menu Installing and functionality is not there. This requires the Command Line Interface, below.
• Command Line Interface is not implemented at all. Needs to be there, should be next major priority.
• Exporting hash sum and HashDeep files needs to be possible.
• The Matching Window interface can use some improvement.
• Translations are not complete.
• Scheduling system should be created so that this can compete with QuickHash-GUI.
