This is an AES encryption code I've gotten from a Java source. This bugs me, as the `Cipher` itself doesn't use any initial vector in it's initialization - thus I can't seem to to the same thing in Python. Can anyone with a Java background help me understand what this actually does?

```
byte key[] = {0x13, 0x00, 0x00, 0x00, 0x08, 0x00, 0x00, 0x00, 0x06, 0x00, 0x00, 0x00, (byte) 0xB4, 0x00, 0x00, 0x00, 0x1B, 0x00, 0x00, 0x00, 0x0F, 0x00, 0x00, 0x00, 0x33, 0x00, 0x00, 0x00, 0x52, 0x00, 0x00, 0x00};
SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
byte[] myIv = {70, 114, 122, 82, 70, 114, 122, 82, 70, 114, 122, 82, 70, 114, 122, 82}
byte[] newIv = cipher.doFinal(myIv);
