Urgent!!!! - Problem in storing encrypte word into SQL Server database

Question

Hi,
I want to encrypt a word using DES algorithm and store in the database.I am using Microsoft SQL Server 2000 database. I have tried giving the datatype as varchar,binary etc. but i am not able to store a byte array.Here is my code. Plz help me to store the encrypted word in the database.
import javax.crypto.Cipher;
   import javax.crypto.BadPaddingException;
   import javax.crypto.IllegalBlockSizeException;
   import javax.crypto.KeyGenerator;
   import java.security.Key;
   import java.security.InvalidKeyException;
   import java.io.*;
   import java.sql.*;
   public class PwdEnc {
        private static String algorithm = "DESede";
        private static Key key = null;
        private static Cipher cipher = null;
        private static void setUp() throws Exception {
            key = KeyGenerator.getInstance(algorithm).generateKey();
            cipher = Cipher.getInstance(algorithm);
        public static void main(String[] args)
           throws Exception {
            setUp();
            byte[] encryptionBytes = null;
            String input = "akshatha34";
            encryptionBytes = encrypt(input);
            try
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               Connection con=DriverManager.getConnection("jdbc:odbc:SQLDB1","sa","projguru");
               Statement st=con.createStatement();
               System.out.println(encryptionBytes);
          //     String s1="Insert into tblLogin values("+encryptionBytes+","+encryptionBytes+")";
               String s1="Insert into tblLogin values("+encryptionBytes+")";
               System.out.println(s1);
               int rs=st.executeUpdate(s1);
               if(rs>=1)
               System.out.println("inserted");
               else
               System.out.println("failed");
          }catch(Exception e){
               System.out.println(e);
               for(int i=0;i<encryptionBytes.length;i++)
                    System.out.println(encryptionBytes);
               System.out.println(encryptionBytes);
private static byte[] encrypt(String input)
throws InvalidKeyException,
BadPaddingException,
IllegalBlockSizeException {
cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] inputBytes = input.getBytes();
return cipher.doFinal(inputBytes);
thanks,

Answer 1

Try using a Prepared statement and setBytes;
PreparedStatment insert = con.prepareStatement("Insert into tblLogin values(?)");
insert.setBytes(1, encryptionBytes);
insert.executeUpdate();
