Javax.servlet.ServletException: javax.crypto.IllegalBlockSizeException: длина ввода должна быть кратна 16 при расшифровк ⇐ JAVA

Как решить описанную ниже проблему.
action.java:
byte[] decValue = c.doFinal(decordedValue);
account_bean fromBean = (account_bean) form;
String account_name = fromBean.getName();
String encrypted_password = fromBean.getPassword();
String account_password = AESencrp.decrypt(encrypted_password.toString().trim());

AESencrp.java:
import java.security.*;
import javax.crypto.*;
import javax.crypto.spec.SecretKeySpec;
import sun.misc.*;
public class AESencrp
{
private static final String ALGO = "AES";
private static final byte[] keyValue =
new byte[] { 'T', 'h', 'e', 'B', 'e', 's', 't',
'S', 'e', 'c', 'r','e', 't', 'K', 'e', 'y' };
public static String encrypt(String Data) throws Exception
{
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.ENCRYPT_MODE, key);
byte[] encVal = c.doFinal(Data.getBytes());
String encryptedValue = new BASE64Encoder().encode(encVal);
return encryptedValue.toString().trim();
}
public static String decrypt(String encryptedData) throws Exception
{
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, key);
byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedData);
byte[] decValue = c.doFinal(decordedValue);
String decryptedValue = new String(decValue);
return decryptedValue.toString().trim();
}
private static Key generateKey() throws Exception
{
Key key = new SecretKeySpec(keyValue, ALGO);
return key;
}
}
