TrustedPeople ストアから x509 証明書を読み取り、それを XML ドキュメントに添付したいと考えています。
RSAKeyValue rsaKey = new RSAKeyValue();
XmlDocument xmlDoc = new XmlDocument();
string filename = "C:/Documents and Settings/sbtho/Desktop/downloads/samp.xml";
string filename1 = "C:/Documents and Settings/sbtho/Desktop/downloads/sampdigsig.xml";
xmlDoc.PreserveWhitespace = false;
xmlDoc.Load(new XmlTextReader(filename));
SignedXml signedXml = new SignedXml(xmlDoc);
signedXml.SigningKey = rsaKey.Key;
Signature xmlSignature = signedXml.Signature;
Reference reference = new Reference("");
XmlDsigEnvelopedSignatureTransform envelope = new XmlDsigEnvelopedSignatureTransform();
XmlDsigC14NWithCommentsTransform envelope1 = new XmlDsigC14NWithCommentsTransform();
reference.AddTransform(envelope);
reference.AddTransform(envelope1);
xmlSignature.SignedInfo.AddReference(reference);
KeyInfo keyInfo = new KeyInfo();
X509Store store = new X509Store(StoreName.TrustedPeople, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly);
X509Certificate2Collection certs = store.Certificates.Find(X509FindType.FindByThumbprint, "ffa8ebf4760ab2d145b8ca21b1de258923e7d9d8", false);
store.Close();
keyInfo.AddClause(rsaKey);
xmlSignature.KeyInfo = keyInfo;
signedXml.ComputeSignature();
XmlElement xmlDigSign = signedXml.GetXml();
xmlDoc.DocumentElement.AppendChild(xmlDoc.ImportNode(xmlDigSign, true));
if (xmlDoc.FirstChild.GetType() == typeof(XmlDeclaration))
xmlDoc.RemoveChild(xmlDoc.FirstChild);
XmlTextWriter xmlWriter = new XmlTextWriter(filename1, new UTF8Encoding(false));
xmlDoc.WriteTo(xmlWriter);
xmlWriter.Close();
これは私が到達した距離です。trustedpeople ストアからの読み取り値です。この証明書を XML ドキュメントに挿入するにはどうすればよいですか?
