Question

I’m trying to generate a hash value of a specific string in MD5 Base64.
Is it possible to do it in a query within SQL Server?

I know there’s a function to generate hashes in HashBytes(Algo,String), but there’s no Base64 option.

Is there?

Thanks!

CREATE FUNCTION dbo.Base64Encode
(
    @bin VARBINARY(MAX)
)
RETURNS VARCHAR(MAX)
AS
BEGIN   
    return CAST(N'' AS XML).value('xs:base64Binary(xs:hexBinary(sql:variable("@bin")))', 'VARCHAR(MAX)')
END

SELECT dbo.Base64Encode(HashBytes('MD5', ItemName))
FROM tblItems
