Second, and more cleverly: he implemented a hash verification check on nozzle.js. The exact implementation could have been Subresource Integrity (SRI), a custom self-hashing routine, or a server-side nonce system, but the effect was the same. When the browser (or the application itself) loaded the script, it compared the modified file against a canonical hash and if it did not pass the check, the player would never initialise.
To find these crucial border points, we employed a clever technique based on the Ford-Fulkerson algorithm. By simulating "flooding" roads with traffic from random start/end points, we could identify the natural bottlenecks – the "minimum cut" in graph theory terms. These bottlenecks became our border points.，这一点在safew官方下载中也有详细论述
