使用ASP.Net加密Cookie[4]

    ——此文章摘自《ASPNET網絡數據庫開發實例精解》定價￥ 特價￥ 詳細>>

    public static void SetEncryptedCookie(String keyString valueString)
    {   //設置使用DES加密後的Cookie
    key = EncryptStringEncrypt(key);
    valueString = EncryptStringEncrypt(valueString);
    SetCookie(keyvalueString);
    }
    public static void SetEncryptedCookie(String key
    String valueStringDateTime expires)
    {   //設置使用DES加密後的Cookie並設置Cookie的有效時間
    key = EncryptStringEncrypt(key);
    valueString = EncryptStringEncrypt(valueString);
    SetCookie(keyvalueStringexpires);
    }
    public static String GetTripleDESEncryptedCookieValue(String key)
    {   //獲取使用TripleDES解密後的Cookie
    key = EncryptStringEncryptTripleDES(key);
    String valueString = GetCookieValue(key);
    valueString = EncryptStringDecryptTripleDES(valueString);
    return(valueString);
    }
    public static String GetEncryptedCookieValue(String key)
    {   //獲取使用DES解密後的Cookie
    key = EncryptStringEncrypt(key);
    String valueString = GetCookieValue(key);
    valueString = EncryptStringDecrypt(valueString);
    return(valueString);
    }
    public static HttpCookie GetCookie(String key)
    {   //通過關鍵字獲取Cookie
    key = HttpContextCurrentServerUrlEncode(key);
    return(HttpContextCurrentRequestCookiesGet(key));
    }
    public static String GetCookieValue(String key)
    {   //通過關鍵字獲取Cookie的value
    String valueString = GetCookie(key)Value;
    valueString = HttpContextCurrentServerUrlDecode(valueString);
    return(valueString);
    }
    }

    ．設計頁面EncryptCookiesaspx

    把應用程序Example__的默認頁面WebFormaspx重命名為 EncryptCookiesaspx並在頁面上添加個Label控件它們的名稱分別為TripleDESCookie EncryptCookie和myCookie分別用來顯示使用TripleDES加密後的Cookie的值使用DES加密後的Cookie的值和 Cookie的原始值頁面EncryptCookiesaspx的設計界面如圖所示
    頁面EncryptCookiesaspx的HTML設計代碼如下
    <asp:Label ID=myCookie Runat=server></asp:Label>
    <asp:Label ID=EncryptCookie Runat=server></asp:Label>
    <asp:Label ID=TripleDESCookie Runat=server></asp:Label>
