Seems like notable SHA-3 candidates should be on a separate line from non-SHA-3 hashes. They're notable for different reasons from the old hash functions, and they're currently new and unanalyzed.

• Existing hash functions: MD2/4/5, SHA-0/1/2, RIPEMD, LM hash, etc.
• Notable SHA-3 candidates: Skein, MD6, CubeHash, etc. (Not every SHA-3 candidate is notable -- some have already been broken, for instance.)

Where wouldSipHash fit in this table? I would say under MAC functions, but I am not an expert on the subject. --Yxejamir (talk)13:58, 19 January 2017 (UTC)[reply]

For a while now,BLAKE2 has been listed as a “common” hash function. Do we have areliable source which supports the assertion that Blake2 is, indeed, a commonly used hash?

The sense I get is that the most commonly used hash these days is SHA256 (SHA-2-256, if you will), since SHA-1 and MD5 (the previously two commonly used hashes) were broken.Samboy (talk)10:24, 1 October 2018 (UTC)[reply]

Poking around, BLAKE2 (as b2sum) isone of the hashes included with theGNU Core Utilities (While SHA-3, as I type this, isn’t; the list is currentlywc,sum, cksum,MD5,SHA1,SHA-2, andBLAKE2). Considering how little coverage cryptographic hashes get in the mainstream press, this counts for something.Samboy (talk)02:49, 2 October 2018 (UTC)[reply]

If we’re going to haveNMAC on this list, I would like to see a Wikipedia article about NMAC (or even just a section inHMAC describing what an NMAC is) written first.Samboy (talk)15:21, 6 October 2018 (UTC)[reply]

This section only talks about password KDFs and password hashing functions (bcrypt andcrypt). These should all be moved to a new section called "Key stretching functions" andHKDF should be added to "Key derivation functions".Catena,Makwa, andyescrypt are just redirects toPassword Hashing Competition and should be removed from the template.Lyra2 is a low quality page and should probably be removed from the template.NotSc00bz (talk)23:52, 2 January 2020 (UTC)[reply]

The KDF section should be named:
"Password hashing/
key stretching functions", moveLM hash into it, and remove key stretching from utilization section since it has its own section now. Then add a new KDF section with justHKDF. I'll make this changes in a week if no one disagrees. We should still think about removingCatena,Makwa,yescrypt, andLyra2 for being just redirects toPassword Hashing Competition or having a low quality page.NotSc00bz (talk)04:19, 4 January 2020 (UTC)[reply]
