XmlDsigC14NTransform クラス
アセンブリ: System.Security (system.security.dll 内)


XmlDsigC14NTransform クラスは、XML ドキュメントの標準形式を表す C14N XML 標準化変換を表します。この変換により、署名者は、XML ドキュメントの標準形式を使用して (デジタル署名の作成に使用される) ダイジェストを作成できます。受信者は、同じ変換による同じ XML ドキュメントの標準形式を使用して XML デジタル署名を検証できます。
コメントを含んでいない XML ドキュメントに署名する必要がある場合は、XmlDsigC14NTransform クラスを使用します。
標準化変換クラスの新しいインスタンスを直接作成することはできません。標準化変換を指定するには、変換を記述する URI (Uniform Resource Identifier) を、SignedInfo プロパティからアクセスできる CanonicalizationMethod プロパティに渡します。標準化変換の参照を取得するには、SignedInfo プロパティからアクセスできる CanonicalizationMethodObject プロパティを使用します。
XmlDsigC14NTransform クラスを表す URI は、XmlDsigC14NTransformUrl フィールドおよび XmlDsigCanonicalizationUrl フィールドによって定義されます。
C14N 変換の詳細については、www.w3.org/tr/xmldsig-core/ の W3C (World Wide Web Consortium) から提供されている XMLDSIG 仕様のセクション 6.5 および 6.6.1 を参照してください。標準化アルゴリズムは、www.w3.org/tr/xml-c14n. の W3C『Canonical XML』の仕様で定義されています。

このセクションには、2 つのコード例が含まれています。最初の例は、デタッチ シグネチャを使用して XML データ以外に署名する方法を示しています。例 1 では、www.microsoft.com/japan の署名を XML ファイルに作成してから、そのファイルを検証します。2 番目の例は、XmlDsigC14NTransform クラスのメンバを呼び出す方法を示しています。
