Hash CrOmp

Hash CrOmp is a small-sized and portable application you can use to calculate the MD5, MD42, MD4 and SHA1 signatures of any files, regardless of their format.

Simple interface and settings

It can also compare the checksums of two files to validate data integrity and find out if the two items are different or the same.
Wrapped in a user-friendly interface made from a small window that lists all options put at your disposal, the program invites you to locate and open an item with the aid of the file browser.

Calculate and compare checksums

Afterward, you can pick the hash type from a drop-down menu and click a button to instantly calculate it. The alphanumerical value can be converted to uppercase or lowercase, as well as copied to the Clipboard with one click.
In order to match a hash against another one, all you have to do is paste the signature of another file in the dedicated field and let Hash CrOmp take care of the rest. There are no other notable options provided by this tool. Unfortunately, it doesn't support batch processing, so it can find out the checksum of only one file at a time.

No installation required

The whole app's packed in a single .exe file that can be saved to a custom directory on the disk or copied to a removable storage unit, in order to directly run it on any PC with as little effort as possible. It doesn't add new entries to the system registry, need DLLs or other components to run, or create files on the HDD without asking for your permission.

Evaluation and conclusion

It didn't put a strain on PC performance in our tests, running on low CPU and RAM. No error dialogs popped up and it didn't freeze or crash. All in all, Hash CrOmp features intuitive options to help you calculate and compare file hashes.
