This just linearly increases the security

In that case, the correct course of action would have been to use a strong password the first time.

This hint isn't really useful. Rather, it's just something you can do if you feel like being inconvenienced.

Actually, they're both wrong. From what I know about AES, it's no better than other forms of encryption when it comes to "nesting". If you do AES once, and then do AES again, you haven't strengthened it any. It ends up being encrypted with just another key no stronger than the strongest key in the chain. It could even end up worse than any of the original keys.

In other words, if you combine keys such as "hello" and "qfhejlhfqm8hvaowhgfimahiwuhfcmilwaf", an attacker might be able to decrypt it with a key like "lkjafeuono".

Basically, if you're not a crypto expert, don't go arbitrarily combining crypto systems. It's usually counter-productive.
