基本上，我在查看 Motorstorm 排行榜时在我的 PS3 上共享数据包。排行榜以 XML 格式发送到我的 ps3，但只有在我获得授权之后。那么有人可以告诉我这三个数据包之间发生了什么以及我如何在浏览器中复制它？

数据包 1 从我的 PS3 到索尼服务器

Packet 2 索尼服务器对我的 PS3 的响应

数据包 3 PS3 对索尼服务器最后一个数据包的响应

我试图在 Firefox 和篡改标头以及 PHP cURL 中复制它，但我一无所获。我认为这与不断变化的随机数、随机数和响应变量有关 >< 请帮助 =)

Nonce、cnonce 等都与HTTP Digest Authentication相关，这是一种无需发送明文密码即可实现认证的认证机制。所以如果你想在你的 PS3 游戏中作弊，我猜你首先必须从 MD5 哈希中破解密码。

而且它不称为 HTTP数据包，在第 7 层，您通常会说请求/响应或类似名称。

随机数nonce和 cnonce看起来像哈希码。

针对作弊者的一种可能的防御机制可能是：

def ps3client_send_score():
    score = "bazillion points"
    nonce = md5(score + "something you don't know about")
    send_to_server(score, nonce)

在服务器端：

def get_client_score(score, nonce):
    if md5(score+"something you don't know about")==nonce:
        accept_score(score)
    else:
        reject_score_and_ban_the_fool_if_he_continues_this()

因此，除非您想花数周时间试图在游戏中找到盐分，否则请忘记它。
