If you select a file to have it’s hash calculated (like after downloading) and enter the ‘Expected Hash Value’ afterwards, it won’t compare the hashes. You have to enter the value first, and then select the file. There should be an ‘AfterUpdate’ event (or equivalent) for the ‘Expected Hash Value’ field to trigger the comparison.
An implemented added in v2.8.3 (not released yet) – see commit https://github.com/tedsmith/quickhash/commit/53d2621b9a6fc55a357ef99ffd737ac31a3ee253 . I not sure if it’s the best way of doing it, but it generally works.
I guess I’d never considered that way round before. But I guess it’s a fair point so I’ll look at adding that. Incidentally, v2.8.2 is the current release. Please don’t use the older versions if you can avoid it.
