Techbits #16: HashCheck - Check the hashes!

I'm sure you would have come across situations where you needed to find out the hash values (like MD5, SHA-1 etc.) of files or directories to validate their integrity. If you had participated in any release readiness review meetings, then you would have needed to fill in the hashes for the files being delivered. Or when you've downloaded something and when you want to verify the file integrity, you would need to verify the hash of the downloaded file against what is published on the site. The utility "HashCheck" comes very hand in such cases.

HashCheck Shell Extension makes it easy for anyone to calculate and verify checksums and hashes from Windows Explorer itself. In addition to integrating file checksumming functionality into Windows, HashCheck can also create and verify SFV files  (and other forms of checksum files, such as .md5 files). It is fast and efficient, with a very light disk and memory footprint. And, of course, it is open source.

http://code.kliu.org/hashcheck/ is where you'd find this utility.
