HashSlash

HashSlash is an intuitive application you can use to calculate the checksums of any files, regardless of their extensions. It supports MD5, SHA1, SHA256, SHA384, SHA512, RIPEMD160 and CRC32 hashes. This type of software helps you verify the integrity of files using these unique IDs.

No setup required, besides .NET Framework

If you already have .NET Framework installed on your computer, you don't need to set up anything else. This tool is packed in a single executable file which you can copy to any part of the hard drive or on a USB flash disk, in order to seamlessly run it on any machine. It doesn't require other DLLs, doesn't create files on the disk without your permission, and doesn't modify Windows registry settings.

Calculate multiple checksums at once

When it comes to the interface, HashSlash adopts a small window with a straightforward look, where you can select one or multiple checksums to take into account, as well as drop a file in the dedicated area while browsing disk directories in your file explorer.
After computing information, the utility brings up another small pane to display the alphanumeric representation of each specified signature, giving you the possibility to copy a selected or all hashes to the Clipboard, in order to paste them into other programs.

Evaluation and conclusion

It computed data swiftly in our tests while remaining light on system resources, thanks to the fact that it needed low CPU and RAM to work properly. No error dialogs popped up and it didn't freeze or crash.
On the other hand, it doesn't integrate support to discover the hashes of multiple files at the same time, nor for printing the listed checksums or exporting them to file. Nevertheless, HashSlash gets the job done and can be easily used.
