SHA-3 hash

SHA-3 hash

(1) By anonymous on 2020-09-12 15:16:13 [link]

a maybe silly question about sha-3 hash. I just download precompiled binary for Windows, sqlite-dll-win32-x86-3330000.zip. The sha-3 hash should be 
according to the download site. However, I checked the hash with another tool, quickhash. It states
to be sha-e hash, for the zipped file. This is quite a difference. 
What am I doing wrong? Thanks in advance for any answer!

For the like-named file downloaded from sqlite.org, I get a 256 bit SHA3 hash of d669a92271ad31bbefe4ba827c3d6621179b1964b5dd1f27c6fbaa9c4cf6a082 and a 512 bit SHA3 hash of 429f5cb2eb6eddaac55599b755bf50513ab1b83a065d83ff24b3873a745e0e138443012d7ee401802f80300ce946e4c2e492dfc9a64181d2133383d7ebbae622 .  The former matches what you claim the website says and the latter is the same length as the "quickhash" result you report but with a different value.  Based on this, I think you have a genuine, uncorrupted .zip file and a strange SHA3 hash calculator.

What happens if you ask Quickhash for the SHA-3 (256 bit) hash? (And what is a "sha-e hash"?)

I suggest having a read of :


This has some standard test examples to test the hash algorithm and software.

The line for the  input abc is:
SHA-3-256	3a985da74fe225b2045c172d6bd390bd855f086e3e9d525b46bfe24511431532

So, if your Windows program, such as quickhash, produces this same result for the 3 character input abc, then it is acceptable. Make sure you input is EXACTLY 3 characters. No spaces, tabs,line feeds or carriage returns.

It may take a few tries to get the right parameters - as you can see from the above sha_testvectors site there are at least 9 combinations.

Quite some time ago I wrote my own file hasher that computes all the available hash functions from the Python hashlib that are available with printing and verification.  This is what it reports for that file:

sha3_256 OK

I would suspect that the hash calculator you are using is malfunctioning.  Is the zip file intact (does it test OK)?
