Not noted in that article is that HashCheck File Extension has been updated by a new developer to include SHA-256 and SHA-512, making it useful once again.  The latest version (2.3.2 at this writing) is available here.

You must have just missed the release of 2.4.0 by about 10 hours :) which adds SHA3, better multithreading, and a few other things.

In any case, I'm glad you find it useful!
