X509Chain.ChainPolicy プロパティ

定義

名前空間:

System.Security.Cryptography.X509Certificates

アセンブリ:

System.Security.Cryptography.dll

ソース:

X509Chain.cs

X.509 証明書チェーンを作成するときに使用する X509ChainPolicy を取得または設定します。

public:
 property System::Security::Cryptography::X509Certificates::X509ChainPolicy ^ ChainPolicy { System::Security::Cryptography::X509Certificates::X509ChainPolicy ^ get(); void set(System::Security::Cryptography::X509Certificates::X509ChainPolicy ^ value); };

public System.Security.Cryptography.X509Certificates.X509ChainPolicy ChainPolicy { get; set; }

member this.ChainPolicy : System.Security.Cryptography.X509Certificates.X509ChainPolicy with get, set

Public Property ChainPolicy As X509ChainPolicy

プロパティ値

X509ChainPolicy

この X.509 チェーンに関連付けられている X509ChainPolicy オブジェクト。

例外

ArgumentNullException

このプロパティに設定されている値が null です。

例

次のコード例では、現在のユーザーの個人用証明書ストアを開き、証明書を選択してから、証明書と証明書チェーン情報をコンソールに書き込みます。 出力は、選択した証明書によって異なります。

//Output chain information of the selected certificate.
X509Chain ^ ch = gcnew X509Chain;
ch->ChainPolicy->RevocationMode = X509RevocationMode::Online;
ch->Build( certificate );
Console::WriteLine( "Chain Information" );
Console::WriteLine( "Chain revocation flag: {0}", ch->ChainPolicy->RevocationFlag );
Console::WriteLine( "Chain revocation mode: {0}", ch->ChainPolicy->RevocationMode );
Console::WriteLine( "Chain verification flag: {0}", ch->ChainPolicy->VerificationFlags );
Console::WriteLine( "Chain verification time: {0}", ch->ChainPolicy->VerificationTime );
Console::WriteLine( "Chain status length: {0}", ch->ChainStatus->Length );
Console::WriteLine( "Chain application policy count: {0}", ch->ChainPolicy->ApplicationPolicy->Count );
Console::WriteLine( "Chain certificate policy count: {0} {1}", ch->ChainPolicy->CertificatePolicy->Count, Environment::NewLine );

//Output chain information of the selected certificate.
X509Chain ch = new X509Chain();
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online;
ch.Build (certificate);
Console.WriteLine ("Chain Information");
Console.WriteLine ("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag);
Console.WriteLine ("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode);
Console.WriteLine ("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags);
Console.WriteLine ("Chain verification time: {0}", ch.ChainPolicy.VerificationTime);
Console.WriteLine ("Chain status length: {0}", ch.ChainStatus.Length);
Console.WriteLine ("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count);
Console.WriteLine ("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine);

'Output chain information of the selected certificate.
Dim ch As New X509Chain()
ch.ChainPolicy.RevocationMode = X509RevocationMode.Online
ch.Build(certificate)
Console.WriteLine("Chain Information")
Console.WriteLine("Chain revocation flag: {0}", ch.ChainPolicy.RevocationFlag)
Console.WriteLine("Chain revocation mode: {0}", ch.ChainPolicy.RevocationMode)
Console.WriteLine("Chain verification flag: {0}", ch.ChainPolicy.VerificationFlags)
Console.WriteLine("Chain verification time: {0}", ch.ChainPolicy.VerificationTime)
Console.WriteLine("Chain status length: {0}", ch.ChainStatus.Length)
Console.WriteLine("Chain application policy count: {0}", ch.ChainPolicy.ApplicationPolicy.Count)
Console.WriteLine("Chain certificate policy count: {0} {1}", ch.ChainPolicy.CertificatePolicy.Count, Environment.NewLine)

注釈

チェーン ポリシーを設定するには、このプロパティを使用します。 たとえば、チェーンを検証する必要がある拡張キー使用法 (EKU) を指定したり、失効チェックを指定したりできます。
