Hashtab, is the most popular utility for validating file checksums on Windows, and now it has come to OS X!
Hashtab is used by hundreds of thousands of people because it's easy, it's fast, and it works.
HashTab supports many hash algorithms such as MD5, SHA1, SHA2, SHA3, RipeMD, Tiger, TigerTree, Gost, eD2K, BTIH and Whirlpool, and most importantly you can find the checksum of your file right where you need it. Right click on your file and you will see the "File Hashes" menu right there.
Hash your file, paste your checksum in the checksum field and see a green check if your file matches or a red X if the file has been corrupted.
What's New in Version 5.1
Added the winner of the NIST hash competition (Keccak) which is now the official SHA3 standard.
Very fast calculations of all of the various hash methods. Love the right click (2 finger click) integration. Hate the fact that you cannot hash folders.
