All Purpose MD5

With the help of All Purpose MD5 you can seamlessly calculate the MD5 checksum of any file, regardless of its format, as well as compare two hashes to find out whether the two files have identical content or not. Apart from MD5, the tool also offers support for SHA1.
This is a Java-based application that gets quickly installed. It's packed in a simple interface made from a normal window divided into two panes for testing and calculating, respectively.

Calculate and verify MD5 and SHA1 checksums

When it comes to computing MD5 signatures, you can select a file or take into account all files from a specific directory, since batch processing is supported. You can enable recursive mode for folders, as well as ask the tool to save the hash into a new file wherever you want on the disk.
The resulted value can be copied to the Clipboard. As far as MD5 testing is concerned, all you have to do is pick a file, write or paste an MD5 checksum, and click a button to compare them.
Results are instantly shown in the main frame. Apart from the fact that you can toggle between MD5 and SHA1 mode, there are no other noteworthy options available here.

Evaluation and conclusion

The tool finished testing and calculation tasks instantly, and its impact on computer performance was minimal in our tests, thanks to the fact that it needed low CPU and RAM to work properly.
However, the application failed to launch in several cases on machines running recent Windows editions. We must also keep in mind that it hasn't been updated for a long time, so it likely has compatibility issues. Other than that, All Purpose MD5 serves its purpose and can be easily handled by anyone with minimum experience in such software.
