在 Linux Docker 容器中运行时无法读取证书 - 适用于 Windows - Can't read certificate when running in Linux Docker container

我正在尝试从SSL证书中读取信息（在这种情况下，我已经通过Chrome保存了StackOverflow的副本），但是由于某种原因，当我构建它并从Linux Docker容器中运行它时，它无法输出任何内容。

在Windows上，输出是我期望的：

但 Docker 容器上同一应用程序的输出如下所示：

E

这是我的代码：

这是 .NET Core （2.2）中的错误，还是我需要在 Linux 下以不同的方式读取证书？

因此，似乎主要问题是双重的：

使用者备用名称"的"友好名称"因操作系统而异。
格式化字符串因操作系统而异。

窗户：

Friendly name: "Subject Alternative Name"
Formatted data:
    DNS Name=*.stackexchange.com
    DNS Name=stackexchange.com

Docker（显然还有Mac）中的Linux：

Friendly name: "X509v3 Subject Alternative Name"
Formatted data:
    DNS:*.stackexchange.com, DNS:stackexchange.com, DNS:stackoverflow.com, DNS:*.stackoverflow.com, DNS:stackauth.com, DNS:sstatic.net, DNS:*.sstatic.net, DNS:serverfault.com, DNS:*.serverfault.com, DNS:superuser.com, DNS:*.superuser.com, DNS:stackapps.com, DNS:openid.stackauth.com, DNS:*.meta.stackexchange.com, DNS:meta.stackexchange.com, DNS:mathoverflow.net, DNS:*.mathoverflow.net, DNS:askubuntu.com, DNS:*.askubuntu.com, DNS:stacksnippets.net, DNS:*.blogoverflow.com, DNS:blogoverflow.com, DNS:*.meta.stackoverflow.com, DNS:*.stackoverflow.email, DNS:stackoverflow.email, DNS:stackoverflow.blog

为了解决问题 #1，我开始使用值而不是友好名称：2.5.29.17

为了解决问题#2，我不得不稍微更新我的正则表达式。虽然它适用于多行数据（Windows），但不适用于Linux/Mac逗号分隔的数据。

新表达式现在为：((DNS:|DNS Name=|CN=)(?<domain>.*?),?(?=s|$))+

综

上所述，我们得到：

感谢Nkosi向我指出这个答案，我已经能够使用PeNet提取证书URL：

var node = Asn1Node.ReadNode(cert.RawData);
urls =
    FlattenNodes(node)
    .Where(n => n.Nodes.Count > 0 && n.Nodes[0] is Asn1ObjectIdentifier && ((Asn1ObjectIdentifier)n.Nodes[0]).FriendlyName == "subjectAltName")
    .SelectMany(n => n.Nodes).OfType<Asn1OctetString>()
    .SelectMany(o => Asn1Sequence.ReadNode(o.Data).Nodes).OfType<Asn1CustomNode>()
    .Select(o => System.Text.Encoding.UTF8.GetString(o.Data))
    .ToArray();

FlattenNodes看起来像哪里

private IEnumerable<Asn1Node> FlattenNodes(Asn1Node parentNode)
{
    yield return parentNode;
    foreach (var childNode in parentNode.Nodes)
    {
        foreach (var grandChildNode in FlattenNodes(childNode))
        {
            yield return grandChildNode;
        }
    }
}

我知道扁平化所有节点可能不是迄今为止最有效的方法，但就我而言，性能并不重要。它只是检查 Kubernetes 集群中的少数证书作为日常 cron 作业。

我很想知道没有第三方库是否可能，特别是因为它在 Windows 上。

在 Linux Docker 容器中运行时无法读取证书 - 适用于 Windows
