下面是我如何让它在IE8中工作的:

Go to the website in question, https://xxx.yyy.com, for instance, Click through until you get to the Certificate error in the browser status line. View the cert, then from the Details tab, select Copy to File. Save to the desktop as xxx.cer, for example, Start, Run, MMC. File, Add/Remove Snap-In, Select Certificates, Click Add, My User Account, then Finish, then OK, Dig down to Trust Root Certification Authorities, Certificates, Right-Click Certificate, Select All Tasks, Import, Select the Save Cert from the Desktop Select Place all Certificates in the following Store, Click Browse, Check the Box that says Show Physical Stores, Expand out Trusted Root Certification Authorities, and select Local Computer there, click OK, Complete the Import, Check the list to make sure it shows up. You will probably need to Refresh before you see it. Exit MMC, Open Browser, select Tools, Delete Browsing History Select all but Inprivate Filtering Data, complete, Go to Internet Options, Content Tab, Clear SSL State, Close browser and reopen and test.

如果您正在进行一些本地测试，并且您在主机文件中添加了一些别名

127.0.0.1 www.mysite.com

并尝试使用上述任何程序，你将失败。原因是您将为localhost导入一个证书。证书URL不匹配。

在这种情况下，您必须生成一个自签名证书，然后按照上面所述导入它。

如果您正在使用Xampp，则可以轻松地生成正确的证书 c: \ xampp \ apache \ makecert.bat

您可以使用CertMgr将证书添加为受信任的发行者，如果是自签名的，则添加为根证书

CertMgr.exe /add CertificateFileName.cer /s /r localMachine root

如何在20个恼人的步骤中让IE8信任自签名证书

Browse to the site whose certificate you want to trust. When told “There is a problem with this website's security certificate.”, choose “Continue to this website (not recommended).” Select Tools➞Internet Options. Select Security➞Trusted sites➞Sites. Confirm the URL matches, and click “Add” then “Close”. Close the “Internet Options” dialog box with either “OK” or “Cancel”. Refresh the current page. When told “There is a problem with this website's security certificate.”, choose “Continue to this website (not recommended).” Click on “Certificate Error” at the right of the address bar and select “View certificates”. Click on “Install Certificate...”, then in the wizard, click “Next”. On the next page select “Place all certificates in the following store”. Click “Browse”, select “Trusted Root Certification Authorities”, and click “OK”. Back in the wizard, click “Next”, then “Finish”. If you get a “Security Warning” message box, click “Yes”. Dismiss the message box with “OK”. Select Tools➞Internet Options. Select Security➞Trusted sites➞Sites. Select the URL you just added, click “Remove”, then “Close”. Now shut down all running instances of IE, and start up IE again. The site’s certificate should now be trusted.

你以前在做什么?对于自签名证书，我通常会在客户机系统上本地安装证书。

您可以使用组策略将证书推送到每个系统。

确保自签名证书与站点URL匹配。如果不这样做，即使在Internet Explorer 8中显式地信任该证书之后，您也将继续得到证书错误(我没有Internet Explorer 7，但Firefox将不管URL不匹配都信任该证书)。

如果这是问题，Internet Explorer 8中的红色“证书错误”框将在您添加证书后显示“不匹配的地址”作为错误。此外，“查看证书”有一个颁发给:标签，显示证书针对哪个URL有效。
