显示X509Certificate,其链元素不在证书库中

Question

我有一个类型的对象,X509Certificate2并希望将其显示给用户.我正在用这个X509Certificate2UI.DisplayCertificate方法做这件事.

我遇到的问题是我想要显示的这个证书是由中间CA颁发的,证书不在机器证书存储区中,但其根目录是.

现在,如果我显示所述证书,则对话框无法构建链 (与我相反,因为我能够X509Chain将中间CA作为额外元素)

如何使用整个链显示证书？

X509Certificate2 endCert = ...;
X509Certificate2 intermediateCA = ...;

X509Chain chain = new X509Chain();
chain.ChainPolicy.ExtraStore.Add(intermediateCA);
chain.Build(endCert); // Whole chain!

X509Certificate2UI.DisplayCertificate(endCert); // Dialog shows: "The issuer of this certificate could not be found."

(我无法/允许将中间CA添加到用户/机器商店!)
(我无法/允许创建我自己的对话框.它必须是默认的Windows对话框!)
(P/Invoke是允许,如果需要)

只是作为一个例子,你可以尝试这些证书上面的测试,但你必须要参考System.Security.dll的X509Certificate2UI.DisplayCertificate:

我相信这应该是某种可能的,因为Internet Explorer也在做同样的事情.您可以使用https://httpd.apache.org/进行尝试(以上证书来自那里)

Answer 1

如果可能的话，您需要做的是使用 CAPI 创建内存中证书存储并将中间证书添加到其中，然后使用对CryptUIDlgViewCertificate 的底层调用以使用临时存储的方式显示对话。
