Java EE AESKey equivalent

What is the equivalent of AESKey in Java EE?


curently i use this code to encrypt


private static byte[] encrypt(byte[] encryptionKey, byte[] plainText) throws Exception {

Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
SecretKeySpec key = new SecretKeySpec(encryptionKey, "AES");
byte[] x = cipher.init(Cipher.ENCRYPT_MODE, key);

return cipher.doFinal(x);


and it returns java.security.InvalidKeyException: Invalid AES key length: .. bytes

Re: Java EE AESKey equivalent

well, SecretKeySpec key = new SecretKeySpec(encryptionKey, "AES"); is same as AESKey


it was just restriction of Java's Cipher that restrict only 128 bit key length, but RIM does not restrict the key length on its AES crypto API..
