Hash will do it. It's possible that two distinct strings will have the same hashed value, but the odds are small enough that they can be ignored (as evidenced by the whole world using hashes for password checks). It'll also save you some storage, because a hex-encoded hash will be 32 characters, rather than however big the web page's content actually is.
