IgorWare Hasher

IgorWare Hasher is a tiny and powerful application designed to help you verify the integrity of SHA1, MD5 and CRC32 hashes of any files, regardless of their format, using verification files. It can also generate checksums.

Installation is not necessary, which makes IgorWare Hasher portable. It means that you can save the app files anywhere on the HDD and just click the EXE to launch the program, or copy it to a removable storage device to run it on any PC. It doesn't add new entries to the Windows registry, leaving it intact.

The interface doesn't contain visually appealing elements, yet it's quite simple to figure out. You can indicate a file on the disk to find out its SHA1, MD5 and CRC32 signature, as well as match these hashes against verification files from the disk to find out if they're identical.

Checksums can be copied to the Clipboard with one click or saved to file. It's possible to calculate SHA1, MD5 and CRC32 signatures for strings of text.

The app can be asked to stay on top of other windows, remember the last window position, and to automatically calculate hashes after dropping files in the main frame. Unless you're running it from a pen drive, you can integrate it with the Windows Explorer shell extension. Plus, all text characters from the hashes can be converted to uppercase.

We haven't come across any stability issues throughout our evaluation, thanks to the fact that IgorWare Hasher didn't freeze, crash or display error messages. It had a good response time and minimal impact on computer performance, using low CPU and memory.

Taking into account its straightforward and powerful features, IgorWare Hasher should meet the requirements of most users looking to generate and verify MD5, SHA1 and CRC32 checksums. Its interface needs some improvements, though.
