Let's assume, an attacker gains access to an encrypted container with a weak password. They start a brute-force attack and I assume they will succeed. To protect any content which has been added to the container after the leak, I decide to change to a stronger password.
However, at this point, it doesn't make sense to just change the password of the container, right? Won't I have to reencrypt everything since the attacker can extract the "master key" of the container which won't change with a password change?
