I have been around the Internet for quite some time, and recently I have noticed a distinct lack of a good file checksum calculator for Windows.

I mean, why hasn't anyone created an easy to use GUI-based file checksum calculator that can compute the CRC32, MD5, and SHA1 hashes of a file?

Well, I solved that issue and made one myself. I threw a program written in VB.NET together one evening and "Checksum" was born.

New Revision! Less Clutter!

It has the following features...
- CRC32
- MD5
- RIPEMD160
- SHA160 aka SHA1
- SHA256
- SHA384
- SHA512
- GUI-based, not ugly command line
- Fully multi-threaded
- Drag-and-Drop your files from Explorer right into the file textbox
- It's free!

New Features!
- Does away with the listbox of different checksum methods and now calculates them all and gives you a listbox containing them all.

Download it here.

These are the hashes of the download file for verification.
