Hi,

I want to encrypt and decrypt the password .
I have the code for encrytion but can anyone help me to get the code
for decrytion using the same API's.

I have used the following code for Encryption

****************************************************************************************************

package com.netapp.hraf.helper;

//import com.certicom.tls.provider.MessageDigest;
import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
//import org.myorg.SystemUnavailableException;
import sun.misc.BASE64Encoder;
import sun.misc.CharacterEncoder;

public final class PasswordServiceHelper
{
 public static PasswordServiceHelper instance;

 public PasswordServiceHelper()
 {
 }

 public synchronized String encrypt(String plaintext) throws Exception
 {
   MessageDigest md = null;
   try
   {
     md = MessageDigest.getInstance("SHA"); //step 2
   }
   catch(NoSuchAlgorithmException e)
   {
     throw new Exception(e.getMessage());
   }
   try
   {
     md.update(plaintext.getBytes("UTF-8")); //step 3
   }
   catch(UnsupportedEncodingException e)
   {
     throw new Exception(e.getMessage());
   }

   byte raw[] = md.digest(); //step 4
   String hash = (new BASE64Encoder()).encode(raw); //step 5
   System.out.println("the password in hash is "+hash);
   return hash; //step 6
 }

 public static synchronized PasswordServiceHelper getInstance() //step
1
 {
   if(instance == null)
   {
      instance = new PasswordServiceHelper();
   }
   return instance;
 }
}
