したがって、主な問題は 2 つあるようです:

問題 #1 を解決するために、value の使用を開始しました わかりやすい名前ではなく:2.5.29.17
問題 2 を解決するには、正規表現を少し更新する必要がありました。複数行のデータ (Windows) では問題なく機能しましたが、Linux/Mac のコンマ区切りデータではうまく機能しませんでした。
新しい式は次のとおりです:((DNS:|DNS Name=|CN=)(?<domain>.*?),?(?=\s|$))+
すべてをまとめると、次のようになります。
const string ALT_NAME_VALUE = "2.5.29.17";
string certificateData = "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";
var secretData = Convert.FromBase64String(certificateData);
string[] urls = null;
var tmp = new X509Certificate2Collection();
tmp.Import(secretData);
var cert = tmp.OfType<X509Certificate2>().FirstOrDefault();
urls = cert.Extensions
.OfType<X509Extension>()
.Where(e => e.Oid.Value == ALT_NAME_VALUE)
// I removed the part appending the original subject because I realise the same
// information is available in the SAN object, so it was just duplicating data
// this also allowed me to combine Format with creating the AsnEncodedData object
.Select(e => new AsnEncodedData(e.Oid, e.RawData).Format(true))
.SelectMany(d => Regex.Matches(d, "((DNS:|DNS Name=|CN=)(?<domain>.*?),?(?=\\s|$))+").OfType<Match>().Where(m => m.Success).Select(m => m.Groups["domain"].Value))

Console.WriteLine("S");
foreach (var r in urls)

これで、Windows と Linux での出力は同じになりました:

Nkosi がこの回答を教えてくれたおかげで、PeNet を使用して証明書の URL を抽出することができました:
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();
どこで FlattenNodes
のように見えます
private IEnumerable<Asn1Node> FlattenNodes(Asn1Node parentNode)
{
yield return parentNode;
foreach (var childNode in parentNode.Nodes)
{
foreach (var grandChildNode in FlattenNodes(childNode))
{
yield return grandChildNode;
}
}
}
すべてのノードをフラット化することがおそらく最も効率的な方法ではないことはわかっていますが、私の場合、パフォーマンスはそれほど重要ではありません。毎日の cron ジョブとして、Kubernetes クラスター内の少数の証明書をチェックするだけです。
特にWindows上にあるため、サードパーティのライブラリなしで可能かどうか知りたい.
