Generate MD5 hash string with T-SQL

Question

Is there a way to generate MD5 Hash string of type varchar(32) without using fn_varbintohexstr

SUBSTRING(master.dbo.fn_varbintohexstr(HashBytes(\'MD5\', \'em         


        

Answer 1

CONVERT(VARCHAR(32), HashBytes('MD5', 'email@dot.com'), 2)

Answer 2

SELECT CONVERT(
      VARCHAR(32),
      HASHBYTES(
                   'MD5',
                   CAST(prescrip.IsExpressExamRX AS VARCHAR(250))
                   + CAST(prescrip.[Description] AS VARCHAR(250))
               ),
      2
  ) MD5_Value;

works for me.

Answer 3

try this:

select SUBSTRING(sys.fn_sqlvarbasetostr(HASHBYTES('MD5',  'email@dot.com' )),3,32) 

Answer 4

None of the other answers worked for me. Note that SQL Server will give different results if you pass in a hard-coded string versus feed it from a column in your result set. Below is the magic that worked for me to give a perfect match between SQL Server and MySql

select LOWER(CONVERT(VARCHAR(32), HashBytes('MD5', CONVERT(varchar, EmailAddress)), 2)) from ...

Answer 5

Use HashBytes

SELECT HashBytes('MD5', 'email@dot.com')

That will give you 0xF53BD08920E5D25809DF2563EF9C52B6

-

SELECT CONVERT(NVARCHAR(32),HashBytes('MD5', 'email@dot.com'),2)

That will give you F53BD08920E5D25809DF2563EF9C52B6

Answer 6

Solution:

SUBSTRING(sys.fn_sqlvarbasetostr(HASHBYTES('MD5','your text')),3,32)
