No. Given a large enough work factor, there literally aren&#x27;t enough resources in the entire universe to brute-force even a single hash. &quot;Hard to imagine&quot; and &quot;limitless&quot; are very different animals.<p>Edit: moreover, the GP has already mentioned that &quot;[brute force] isn&#x27;t a zero-cost effort in terms of time,&quot; even if you have access to humongous amounts of processing power. The point of encryption isn&#x27;t to protect data forever; just long enough for them to become uninteresting.
