DiamondCS MD5

DiamondCS MD5 is a lightweight and portable application that gives you the possibility to seamlessly calculate the MD5 checksum of any files, regardless of their type. It also has a feature dedicated to text.

Simple interface for MD5 checksums

This kind of program is practical for verifying file integrity before attempting to download large items from the Internet, for example. By comparing the two hashes, you can find out whether they match, in order to make sure you're downloading the right file. Otherwise, it can be incomplete.
When it comes to the interface, DiamondCS MD5 adopts a standard window with a rudimentary look and neatly structured layout, showing an overview of all options available.

Easily check file and text integrity

You can resort to the file browser to locate and find a file, as well as click a button to instantly find out its MD5 signature. Similarly, you can type or paste text in the dedicated field, switch to text mode, and reveal the MD5 hash easily.
This alphanumerical value can be selected and copied to the Clipboard by opening the right-click menu or by triggering the global keyboard shortcut. However, it doesn't implement settings for calculating the MD5 checksums for multiple files at the same time.

Portable application

The entire tool's packed in a single .exe file that can be dropped anywhere on the disk or copied to a removable storage unit, in order to directly run it on any computer with as little effort as possible.
It doesn't add new entries to your system registry, create files on the disk without permission, or need DLLs or other components to run. In order to get rid of it, you simply have to delete its executable.

Evaluation and conclusion

As previously mentioned, calculations were instantly made in our tests. The program remained minimal on system resources consumption during this time, since it needed a low amount of CPU and RAM to work properly. It was stable throughout its runtime.
To wrap it up, DiamondCS MD5 may not have a particularly rich set of options, but it delivers a straightforward method for finding out the MD5 hashes of files and strings of characters. Plus, it's freeware.
