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


XmlDsigEnvelopedSignatureTransform クラスは、ダイジェストを計算する前に <Signature> 要素を XML ドキュメントから削除します。この変換では、XML デジタル署名要素を除き、XML ドキュメントのすべての要素を署名および検証できます。
署名を作成して XML ドキュメントに挿入することはできますが、その場合、ドキュメントには追加の要素が存在することになります。ドキュメントがこのように変更されているため、埋め込まれている署名で検証しようとするとエラーになります。この変換では <Signature> 要素が削除され、ドキュメントを元の形式で検証できるようになります。
エンベロープ シグネチャを作成する場合は必ず、XmlDsigEnvelopedSignatureTransform クラスを使用してください。
エンベロープ署名変換の詳細については、www.w3.org/TR/xmldsig-core/ の W3C から提供されている XMLDSIG 仕様のセクション 6.6.4 を参照してください。

このセクションには、2 つのコード例が含まれています。1 番目の例では、エンベロープ シグネチャを使用して XML ファイルに署名する方法を示します。2 つ目のコード例には、XmlDsigEnvelopedSignatureTransform クラスのメンバを使用した方法が示されています。
