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

请参阅微软的文档:

https://learn.microsoft.com/en-us/windows-hardware/drivers/install/using-certmgr-to-install-test-certificates-on-a-test-computer

我在使用web服务时也遇到了同样的问题。在这里，微软有一个(很长的)演示，告诉您如何在客户端安装东西，基本上说您的自签名证书是可以的。最后，我花了30美元，从Godaddy.com上买了一个完整的证书。

附注:我知道你可以编写错误消息，但出于测试原因，我们不想这样做。

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。

伙计，今天我花了几个小时来解决这个问题。无论我在IE 8中做了什么，问题仍然存在。IE安装的证书出现在客户端PC的“受信任的根证书颁发机构”中，但IE仍然报错。

以下是我发现的解决方案:

在web服务器上:

Win+R, MMC，回车。 文件，添加-删除管理单元，证书，添加，管理证书:我的用户帐户， 完成。 导航到“证书-当前用户/受信任的根证书颁发机构/证书”。 找到您的证书，右键单击All tasks / Export。 不，不要导出私钥 "DER编码二进制X.509 (.CER)" 将文件保存在某个地方。 将新创建的. cer文件传输到客户端PC上。

在客户端机器上:

Win+R, MMC, Enter. File, Add-Remove snap-in, Certificates, Add, Manage certificates for: my user account, Finish, OK. Navigate to "Certificates - current user / Trusted Root Certification Authorities / Certificates". Right-click on Certificates container, All tasks / Import Choose your .CER file you've transferred from the server machine. On the next screen, choose "Place all certificates in the following store", click "Browse", check "Show physical stores", then choose "Trusted Root Certification Authorities / Local Computer". Press "Finish" finally. In Internet Explorer: Tools - Delete browsing History, In Internet Explorer: Tools - Internet options - "Content" tab - Clear SSL state button.

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.

如何安装CA根证书，而不是网站证书:(IE8, Win7)

When you bring up the certificate details you are looking at the website cert, and not the CA cert. The General tab will say, "This certificate cannot be verified..." You need to select the CA by clicking on the Certification Path tab, and selecting the top most cert in the path. It should have a red X icon, and should say, "This CA Root certificate is not trusted because..." Click the View Certificate button, and on this new General tab you should see, "This CA Root is not trusted..." This is the certificate that you want to import into the Trusted Root Certificate Authority.

一旦您导入了CA，您就不需要再导入常规的网站证书，该证书将与您刚刚导入的CA匹配，IE会将一切视为正常工作。您不需要以管理员身份运行IE，也不需要先将站点添加到可信站点。导入完成后需要重新启动IE。
