In the first part of the article there was a reference to "Keyed cryptographic hash functions", with a link to the simple "cryptographic hash functions". HMAC looks to me much more accurate, but a check into the reference book (Zdziarski, Jonathan) was not successful. The book only speaks about the use of crypto hash to improve security.

The section on deleting the salt to provide "key strengthening" seems suspect. Deleting the salt and requiring legitimate users to brute force attack their own stuff doesn't seem reasonable. The quoted links are to offline sources. (Journals/books) Can anyone find an online source for this? And is there a known implementation that uses this technique today? The citations don't directly support this paragraph. <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Javacodehead|Javacodehead]] ([[User talk:Javacodehead#top|talk]] • [[Special:Contributions/Javacodehead|contribs]]) 19:31, 30 December 2019 (UTC)</small> <!--Autosigned by SineBot-->

This whole article is incomprehensible to someone who doesn't yet know the subject area. The diagram in particular is very confusing with no indication of what the input is, weather the multiple keys are the same or different, I'm very confusingly although it says the output of each stage is input to the next neither the output nor the input are connected to anything.
