Java Card

hello,

I am working with a applet which give data and I would like encrypt this data with DES. Problem is that I use JCWDE which accept only "ALG_DES_CBC_ISO9797_M2" for DES encryption and I don't found the same thing with java.crypto.
I have tested that:

cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");

but I need AlgorithmParameter and I can't use that with JavaCard.

There is another solution?


card code:

	public void initialisation(){
        key = (DESKey)KeyBuilder.buildKey(KeyBuilder.TYPE_DES,KeyBuilder.LENGTH_DES, false);
        key.setKey(Crypto, (short)0);
        ecipher = Cipher.getInstance(Cipher.ALG_DES_CBC_ISO9797_M2,false);
		
	}
	
	// decrypt method
	public byte[] decrypter(byte[] aDecrypter){
		ecipher.init(key, Cipher.MODE_DECRYPT);
		donneeDecrypte = new byte[aDecrypter.length]; 
		ecipher.doFinal(aDecrypter, (short)0, (short)aDecrypter.length, donneeDecrypte, (short)0);	
		return donneeDecrypte;
	}
	
	//encrypt method
	public byte[] cryter(byte[] Crypter){
			
		ecipher.init(key, Cipher.MODE_ENCRYPT);
		
		short taille = (short)Crypter.length;
		short temp = (short) ( taille & 0x0007 );
		taille = (short) (taille + (8 - temp));
	
		donneeCrypter = new byte[taille];
		short toto = ecipher.doFinal(Crypter, (short)0, (short)Crypter.length, donneeCrypter, (short)0);
		ecipher.
		return donneeCrypter;
	}

Client code:

	public void initialiserCrypto(){


		
		
		KeyGenerator keyGen;
		try {
			keyGen = KeyGenerator.getInstance("DES");
			keyGen.init(56);
			key = keyGen.generateKey();
			
			crypto = key.getEncoded();
		} catch (NoSuchAlgorithmException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}

        
        
        try {
			cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");		
			//cipher = Cipher.getInstance("DES");
		} catch (NoSuchAlgorithmException e) {
			e.printStackTrace();
		} catch (NoSuchPaddingException e) {
			e.printStackTrace();
		} 
	}
	
	// decrypt method
	public byte[] decrypter(byte[] aDecrypter) {

		AlgorithmParameters params;
		try {
			params = AlgorithmParameters.getInstance("DES");
			params.init(encodedParams);
			cipher.init(Cipher.DECRYPT_MODE, key, params);
			return cipher.doFinal(aDecrypter);
		} catch (NoSuchAlgorithmException e1) {
			e1.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (InvalidKeyException e) {
			e.printStackTrace();
		} catch (InvalidAlgorithmParameterException e) {
			e.printStackTrace();
		} catch (IllegalBlockSizeException e) {
			e.printStackTrace();
		} catch (BadPaddingException e) {
			e.printStackTrace();
		}
	
		return null;
	}
	
	//encrypt method
	public byte[] cryter(byte[] Crypter) {
		
		
		try {
			cipher.init(Cipher.ENCRYPT_MODE, key);
		} catch (InvalidKeyException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
			
		
		short taille = (short)Crypter.length;
		short temp = (short) ( taille & 0x0007 );
		taille = (short) (taille + (8 - temp));

		
		
		donneeCrypter = new byte[taille];
		try {
			encodedParams = cipher.getParameters().getEncoded();
			cipher.doFinal(Crypter, (short)0, (short)Crypter.length, donneeCrypter, (short)0);
		} catch (ShortBufferException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalBlockSizeException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (BadPaddingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		

		return donneeCrypter;
	}

somebody can help me?
