  Nice question. The longest hash had to be correct, so it was rather easy (counting the characters to check there were actually 64 was the only hard part).

  But did you hash the string as varchar or as nvarchar? They produce different answers of course. It might have been fun to list both sets of hashes and ask people to choose 2, just to make people think a little harder.

  Don't know how many bytes it was but it was the longest.

  varchar, though I thought about nvarchar. Thought that might not be fair.

  Steve, I'd like to see your code because I can't duplicate it. I ran the following:

  DECLARE @HashThis VARCHAR(20) = 'January 1, 2016';

  SELECT 'MD2' AS HashType, hashbytes('MD2',@HashThis) AS HashVal

  UNION

  SELECT 'MD4', hashbytes('MD4',@HashThis)

  UNION

  SELECT 'MD5', hashbytes('MD5',@HashThis)

  UNION

  SELECT 'SHA', hashbytes('SHA',@HashThis)

  UNION

  SELECT 'SHA1', hashbytes('SHA1',@HashThis)

  UNION

  SELECT 'SHA2-256', hashbytes('SHA2-256',@HashThis)

  UNION

  SELECT 'SHA2-512', hashbytes('SHA2-512',@HashThis);

  And got this as text output:

  HashType HashVal

  -------- ------------------------------------------------------------------------ ...

  MD2 0x597769E83A509A788FC891AD451B102B

  MD4 0x760C51EFC11D5B932BDCA99ED0B889CD

  MD5 0xF1A4456FAF93F6FD842344D0AC06D7A1

  SHA 0xD186F5A70C77B99E0FB644C86066E267218A1BC8

  SHA1 0xD186F5A70C77B99E0FB644C86066E267218A1BC8

  SHA2-256 NULL

  SHA2-512 NULL

  (7 row(s) affected)

  I find it odd that I'm getting nulls for the SHA2 hashbytes. This is on SQL Server 2014 Developer Edition with SP1 (12.0.4100.1). Makes me wonder if something is funky about my installation and I just haven't noticed it yet.

  +1 different results with my SQL Server 2014 RTM Express

  declare @val varchar(512)

  set @val = convert(varchar(512),'January 1, 2016')

  select HASHBYTES('SHA2_256',@val)

  select HASHBYTES('SHA2_512',@val)

  I am getting :

  0x3B26AECCDA7B29EEE926C93A32EB0EEBA212896EF85F63EBE2206C04175C956F

  and

  I think I have done some errors in my code ( logical it is 2016-01-05 00:54... or I am tired )

  Have a nice day
