我试图了解如何在ASP.NET Core 2.1中加密Cookie的内容。
如果我正在使用IDataProtector Protect
方法对Cookie的内容进行加密,那么我已经读到,如果将网站移至运行在服务器场中的其他服务器,则Unprotect
方法将无法解密。 Azure等
如果是这样,并且我不想使用Redis(或移动密钥),并且能够使用一种简单的方法来加密内容,我将如何处理?
这是我当前的代码(使用IDataProtector):
public static void SetEncryptedCookie()
{
var cookieData = new Dictionary<string, string>()
{
{ "a", "123" },
{ "b", "xyz" },
{ "c", DateTime.Now.ToString() },
{ "UserID", "unique-number-789" }
};
CookieOptions options = new CookieOptions
{
Expires = DateTime.Now.AddDays(90)
,HttpOnly = true
,Secure = true
,IsEssential = true // GDPR
,Domain = ".example.org"
};
// _dataProtector = provider.CreateProtector("somepurpose");
string protectedCookie = _dataProtector.Protect(cookieData);
// IHttpContextAccessor _accessor
// write cookie to http response
_accessor.HttpContext.Response.Cookies.Append("mycookie", protectedCookie, options);
// retrieve encrypted cookie contents.
// ##### this will fail in server farms.
var cookieEnc = _accessor.HttpContext.Request.Cookies["mycookie"];
var cookieDec = _dataProtector.Unprotect(cookieEnc);
}
答案 0 :(得分:0)
在public void ConfigureServices(IServiceCollection services)
做
DirectoryInfo SharedKeysDataProtectionDirectory = new DirectoryInfo("shared/KeysDataProtection/Directory");
services.AddDataProtection()
.SetApplicationName("WebFarmSharedAppName")
.PersistKeysToFileSystem(SharedKeysDataProtectionDirectory);
