 declare @md5 varchar(40);

--garbled

 SELECT @md5 = hashbytes('MD5', '1') ;

 print @md5; 

--normal

 SELECT @md5=sys.fn_VarBinToHexStr(hashbytes('MD5', '1'))

 print SUBSTRING(@md5, 3, 35);

 print UPPER(SUBSTRING(@md5, 3, 35));

 

 SELECT @md5=sys.fn_VarBinToHexStr(hashbytes('SHA1', '1'))

 print SUBSTRING(@md5, 3, 35);
