X500DistinguishedNameとは? わかりやすく解説

X500DistinguishedName クラス

メモ : このクラスは、.NET Framework version 2.0新しく追加されたものです。

X509 証明書識別名を表します。このクラス継承できません。

名前空間: System.Security.Cryptography.X509Certificates
アセンブリ: System (system.dll 内)
構文構文

Public NotInheritable Class
 X500DistinguishedName
    Inherits AsnEncodedData
Dim instance As X500DistinguishedName
public sealed class X500DistinguishedName :
 AsnEncodedData
public ref class X500DistinguishedName sealed

解説解説

このクラスは、SubjectName プロパティ (発行され証明書受け取主体者名) や IssuerName プロパティ (証明書の発行者名) に対す拡張機能のようなものです。X.500 は、分散ディレクトリ サービス国際標準となってます。識別名には次の形式使用されます。

[X500:/C=CountryCode/O=Organization/OU=OrganizationUnit/CN=CommonName]

フィールド長は、次のように制限されています。

次のガイドライン適用されます。

たとえば、[X500:/ C=US/ O=Microsoft/ OU=WGA/ CN=TedSt] のように指定します
