Ragazzi ho torvato questa classe sul web che crypta la password,vorrei eliminare il costruttore, chi mi modifica questa classe oppure mi spiega come fare?....vorrei utilizzarla senza il costruttore....
codice:
package beans;
import java.security.spec.*;
import javax.crypto.*;
import javax.crypto.spec.*;
import java.io.*;

public class Crypt
{
	Cipher ecipher;
	Cipher dcipher;

	// 8-byte Salt
	byte[] salt = {(byte)0xA9, (byte)0x9B, (byte)0xC8, (byte)0x32,
                (byte)0x56, (byte)0x35, (byte)0xE3, (byte)0x03
  };

	// Iteration count
	int iterationCount = 19;

	public Crypt(String passPhrase)
	{
		try
		{
			// Create the key
			KeySpec keySpec = new PBEKeySpec(passPhrase.toCharArray(), salt, iterationCount);
			SecretKey key = SecretKeyFactory.getInstance("PBEWithMD5AndDES").generateSecret(keySpec);
			ecipher = Cipher.getInstance(key.getAlgorithm());
			dcipher = Cipher.getInstance(key.getAlgorithm());

			// Prepare the parameter to the ciphers
			AlgorithmParameterSpec paramSpec = new PBEParameterSpec(salt, iterationCount);

			// Create the ciphers
			ecipher.init(Cipher.ENCRYPT_MODE, key, paramSpec);
			dcipher.init(Cipher.DECRYPT_MODE, key, paramSpec);
		}
		catch (java.security.InvalidAlgorithmParameterException e)
		{
		}
		catch (java.security.spec.InvalidKeySpecException e)
		{

		catch (javax.crypto.NoSuchPaddingException e)
		{
		}
		catch (java.security.NoSuchAlgorithmException e)
		{
		}
		catch (java.security.InvalidKeyException e)
		{
		}
	}

	public String encrypt(String str)
	{
		try
		{
			// Encode the string into bytes using utf-8
			byte[] utf8 = str.getBytes("UTF8");

			// Encrypt
			byte[] enc = ecipher.doFinal(utf8);

			// Encode bytes to base64 to get a string
			return new sun.misc.BASE64Encoder().encode(enc);
		}
		catch (javax.crypto.BadPaddingException e)
		{
		}
		catch (IllegalBlockSizeException e)
		{
		}
		catch (UnsupportedEncodingException e)
		{
		}
		catch (java.io.IOException e)
		{
		}
		return null;
	}

	public String decrypt(String str)
	{
		try
		{
			// Decode base64 to get bytes
			byte[] dec = new sun.misc.BASE64Decoder().decodeBuffer(str);

			// Decrypt
			byte[] utf8 = dcipher.doFinal(dec);

			// Decode using utf-8
			return new String(utf8, "UTF8");
		}
		catch (javax.crypto.BadPaddingException e)
		{
		}
		catch (IllegalBlockSizeException e)
		{
		}
		catch (UnsupportedEncodingException e)
		{
		}
		catch (java.io.IOException e)
		{
		}
		return null;
	}

        /*
	public static void main(String[] args)
	{
		Crypt a = new Crypt("prova");
		//a.encrypt(password);
		//System.out.println(Crypt("prova"));
		a.encrypt("prova");
		a.decrypt("prova");
	}
