Check xml file signature with parent's public key

I'm creating a code that verifies the signature of an xml file through the public key of the certification authority of the certificate that signed that xml. For some reason when I check with the public key of the certificate that signed it, everything goes well, but when I use the public key of the parent, it says that the signature is invalid.
I show below both the code that signs and what it verifies.
Comments:
The CA is self-signed by an AD CS.
I don't want the crl of the certificates to be validated.
private void signBtn_Click(object sender, EventArgs e)
{
XmlDocument doc = new XmlDocument();
doc.Load(#"C:\urnaData\votos.xml");
X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly);
X509Certificate2Collection col = store.Certificates.Find(X509FindType.FindByIssuerName, "CA das Urnas - CNE", true);
foreach (X509Certificate2 x509 in col)
{
SignXmlDoc(doc, x509);
File.WriteAllText(#"C:\urnaData\votes-signed.xml", doc.OuterXml);
}
store.Close();
}
public static void SignXmlDoc(XmlDocument doc, X509Certificate2 cert)
{
SignedXml signedXml = new SignedXml(doc);
signedXml.SigningKey = cert.GetRSAPrivateKey();
Reference reference = new Reference();
reference.Uri = "";
reference.AddTransform(new XmlDsigEnvelopedSignatureTransform());
signedXml.AddReference(reference);
KeyInfo keyInfo = new KeyInfo();
keyInfo.AddClause(new KeyInfoX509Data(cert));
signedXml.KeyInfo = keyInfo;
signedXml.ComputeSignature();
XmlElement xmlSig = signedXml.GetXml();
doc.DocumentElement.AppendChild(doc.ImportNode(xmlSig, true));
}
private void testSign_Click(object sender, EventArgs e)
{
X509Store store = new X509Store(StoreName.Root, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly);
X509Certificate2Collection col = store.Certificates.Find(X509FindType.FindByIssuerName, "CA das Urnas - CNE", true);
foreach (X509Certificate2 x509 in col)
{
XmlDocument doc = new XmlDocument();
doc.Load(#"C:\urnaData\votes-signed.xml");
MessageBox.Show(ValidateXMLSignature(doc, x509).ToString());
}
store.Close();
}
public static bool ValidateXMLSignature(XmlDocument doc, X509Certificate2 cert)
{
try
{
SignedXml signedXml = new SignedXml(doc);
XmlNode signatureNode = doc.GetElementsByTagName("Signature")[0];
signedXml.LoadXml((XmlElement)signatureNode);
return signedXml.CheckSignature(cert, true);
}
catch
{
return false;
}
}

For some reason when I check with the public key of the certificate that signed it, everything goes well, but when I use the public key of the parent, it says that the signature is invalid.
That sounds like everything is working correctly. The parent/CA didn't sign the document, so their public key can't verify it. All you can do is ask two different questions:
Does /this/ certificate's public key verify the signature.
Does /this/ certificate's issuance chain (see X509Chain) say that /this other/ certificate was its direct issuer? (s_parentCertBytes.SequenceEqual(chain.ChainElements[1].Certificate.RawData))
If both return true, then you have effectively written an issuer-pinning routine. But you can't do it without the public key of the actual signing certificate. (The easiest way to internalize that is to realize that the CA and the issued cert don't need to use the same algorithm family... e.g. the CA could have an ECDSA-based key and the issued cert have an RSA-based key... so there's no way you can sensibly ask if the ECDSA public key of the CA can corroborate the RSA signature.)

Sign xml request using non exportable private key from etoken c#

I am working with digital signature. We have to generate xml request and sign the request using private key. The private key to be taken from etoken which is non exportable. My findings showed that private key cannot be extracted when it is marked as non exportable. In this case, how can I sign the xml request. Please help.

Finally I got the solution. Took a while as the requirement was bit rare. This link https://www.codeproject.com/Articles/240655/Using-a-Smart-Card-Certificate-with-NET-Security-i helped me to get the solution. Please refer to below code. For SignXml() method, please refer this msdn link https://msdn.microsoft.com/en-us/library/ms229745(v=vs.110).aspx
X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
store.Open(OpenFlags.MaxAllowed);
// find cert by thumbprint
var foundCerts = store.Certificates.Find(X509FindType.Thumbprint, "12345", true);
if (foundCerts.Count == 0)
return;
var certForSigning = foundCerts[0];
store.Close();
// prepare password
var pass = new SecureString();
var passwordstring = "password";
var chararr = passwordstring.ToCharArray();
foreach (var i in chararr)
pass.AppendChar(i);
// take private key
var privateKey = certForSigning.PrivateKey as RSACryptoServiceProvider;
// make new CSP parameters based on parameters from current private key but throw in password
CspParameters cspParameters = new CspParameters(1,
privateKey.CspKeyContainerInfo.ProviderName,
privateKey.CspKeyContainerInfo.KeyContainerName,
new System.Security.AccessControl.CryptoKeySecurity(),
pass);
RSACryptoServiceProvider rsaCryptoServiceProvider = new RSACryptoServiceProvider(cspParameters);
XmlDocument xmlDoc = new XmlDocument();
// Load an XML file into the XmlDocument object.
xmlDoc.PreserveWhitespace = true;
xmlDoc.Load(path);
// Sign the XML document.
SignXml(xmlDoc, rsaCryptoServiceProvider);

Sign XML with digital signature

I'm working with some web-service which requires digitally signed XML to be posted via HTTP post request.
They gave me only one file (key.dat) which I should apply to my XML.
How can I do it?

You can take a look over here:
private static XmlElement GetXmlDigitalSignature(XmlDocument x, AsymmetricAlgorithm key)
{
var signedXml = new SignedXml(x) { SigningKey = key };
var reference = new Reference { Uri = "", TransformChain = new TransformChain(), };
reference.AddTransform(new XmlDsigEnvelopedSignatureTransform());
signedXml.AddReference(reference);
signedXml.ComputeSignature();
return signedXml.GetXml();
}
var signature = GetXmlDigitalSignature(xmlDocument, algorithm);
xmlDocument.FirstChild.AppendChild(xmlDocument.ImportNode(signature, true));

How to make WCF Client conform to specific WS-Security - sign UsernameToken and SecurityTokenReference

I need to create a wcf client to call a service that I have no control over.
I have been given a wsdl and a working soapui project.
The service uses both a username/password and a x509 certificate.
UPDATE
I now understand what the problem is, but am still unsure what steps I need to take to be able to create the required message, so any help would be much appreciated.
I need to sign both the UsernameToken and the SecurityTokenReference.
The code I had to create the custom binding has been removed from this post as its no longer used. I no longer add a SecurityBindingElement to the binding, instead I add a new behaviour that writes the security element into the header.
So the security node is created from scratch by subclassing the SignedXml class, adding signing references and then calling ComputeSignature to create the Signature node within the Security header.
You need to pass the xml to sign into the SignedXml constructor for this to work. It is no problem passing in the UsernameToken and this appears to be signed correctly.
The problem is that the SecurityTokenReference is only created when ComputeSignature() is called, so I'm not able to add a signing Reference to this element, as it does not exist at the time it is required (within the overridden GetIdElement method of SignedXml which is called prior to ComputeSignature())
The code I'm using to create the signature block to insert into the Security header is as follows
string certificatePath = System.Windows.Forms.Application.StartupPath + "\\" + "Certs\\sign-and- enc.p12";
XmlDocument xd = new XmlDocument();
xd.LoadXml(xml);
// Set Certificate
System.Security.Cryptography.X509Certificates.X509Certificate2 cert = new X509Certificate2(certificatePath, "password");
MySignedXml signedXml = new MySignedXml(xd);
signedXml.SigningKey = cert.PrivateKey;
// Create a new KeyInfo object.
KeyInfo keyInfo = new KeyInfo();
keyInfo.Id = "";
MemoryStream keyInfoStream = new MemoryStream();
XmlWriter keyInfoWriter = XmlWriter.Create(keyInfoStream);
WSSecurityTokenSerializer.DefaultInstance.WriteKeyIdentifierClause(keyInfoWriter, new LocalIdKeyIdentifierClause("token_reference", typeof(X509SecurityToken)));
keyInfoWriter.Flush();
keyInfoStream.Position = 0;
XmlDocument keyInfoDocument = new XmlDocument();
keyInfoDocument.Load(keyInfoStream);
XmlAttribute attrib = keyInfoDocument.CreateAttribute("ValueType");
attrib.InnerText = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3";
keyInfoDocument.ChildNodes[1].ChildNodes[0].Attributes.Append(attrib);
KeyInfoNode keyInfoNode = new KeyInfoNode();
keyInfoNode.LoadXml(keyInfoDocument.DocumentElement);
keyInfo.AddClause(keyInfoNode);
// Add the KeyInfo object to the SignedXml object.
signedXml.KeyInfo = keyInfo;
// Need to use External Canonicalization method.
signedXml.SignedInfo.CanonicalizationMethod = "http://www.w3.org/2001/10/xml-exc-c14n#";
// Create a reference to be signed.
Reference reference = new Reference();
reference.Uri = "#UsernameToken-1";
XmlDsigEnvelopedSignatureTransform env = new XmlDsigEnvelopedSignatureTransform();
env.Algorithm = "http://www.w3.org/2001/10/xml-exc-c14n#";
reference.AddTransform(env);
reference.DigestMethod = "http://www.w3.org/2000/09/xmldsig#sha1";
signedXml.AddReference(reference);
Reference reference2 = new Reference();
reference2.Uri = "#token_reference";
XmlDsigEnvelopedSignatureTransform env2 = new XmlDsigEnvelopedSignatureTransform();
env2.Algorithm = "http://www.w3.org/2001/10/xml-exc-c14n#";
reference2.AddTransform(env2);
reference2.DigestMethod = "http://www.w3.org/2000/09/xmldsig#sha1";
signedXml.AddReference(reference2);
// Add the Signature Id
signedXml.Signature.Id = "MYSIG_ID";
// Compute the signature.
signedXml.ComputeSignature();
XmlElement xmlDigitalSignature = signedXml.GetXml();
where the xml variable is the the UsernameToken xml string, and the MySignedXml class is a subclassed SignedXml with the GetIdElement method overridden (to try to find and correctly refreence the non-existant SecurityTokenReference)
I've spend days researching and testing this now, and unfortunately the company supplying the service isn't any help - but I need to use their service.

We were supplied with some documentation. The security section is copied below
The following security must be applied to each request in the following order:
A wsse:UsernameToken must be included and contain:
The Agent‟s Portal Username for the value of the wsse:Username element
The Agent‟s Portal Password for the value of the wsse:PasswordText (clear text) in the Password element
A Signature block:
Digital Signatures are created using x509 certificates. Each software provider is required to hold and protect a valid certificate and private key issued by [To Be Determined]. With each service request the software must:
Include the Certificate that matches the private key used for signing as a wsse:BinarySecurityToken and use it as the wsse:SecurityTokenReference for the Signature
Sign the wsse:BinarySecurityToken
Sign the wsse:UsernameToken
Use Canonicalization Method Algorithm: http://www.w3.org/2001/10/xml-exc-c14n#
Use Signature Method Algorithm: http://www.w3.org/2000/09/xmldsig#rsa-sha1
Use Digest Method Algorithm: http://www.w3.org/2000/09/xmldsig#sha1
Update
Image of the SoapUI configuration I was initially given

Finally sorted the problem today. In terms of terminology, it is not the SecurityTokenReference that I need to sign, but the Binary Security Token.
In order to do this I needed to hide the certificates for Initiator and Recipient and add a signed supporting token.
I went back to using configuration to create and sign the message, rather than trying to add the signature manually.
Other problem that would have stopped this from working is that I had an incorrect namespace on my custom 'Messaging' header, so be mindful of namespaces, I didn't think they would be as important as what they are.
The code to create the binding follows
private System.ServiceModel.Channels.Binding GetCustomBinding()
{
System.ServiceModel.Channels.AsymmetricSecurityBindingElement asbe = new AsymmetricSecurityBindingElement();
asbe.MessageSecurityVersion = MessageSecurityVersion.WSSecurity11WSTrust13WSSecureConversation13WSSecurityPolicy12;
asbe.InitiatorTokenParameters = new System.ServiceModel.Security.Tokens.X509SecurityTokenParameters { InclusionMode = SecurityTokenInclusionMode.Never };
asbe.RecipientTokenParameters = new System.ServiceModel.Security.Tokens.X509SecurityTokenParameters { InclusionMode = SecurityTokenInclusionMode.Never };
asbe.MessageProtectionOrder = System.ServiceModel.Security.MessageProtectionOrder.SignBeforeEncrypt;
asbe.SecurityHeaderLayout = SecurityHeaderLayout.Strict;
asbe.EnableUnsecuredResponse = true;
asbe.IncludeTimestamp = false;
asbe.SetKeyDerivation(false);
asbe.DefaultAlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Basic128Rsa15;
asbe.EndpointSupportingTokenParameters.Signed.Add(new UserNameSecurityTokenParameters());
asbe.EndpointSupportingTokenParameters.Signed.Add(new X509SecurityTokenParameters());
CustomBinding myBinding = new CustomBinding();
myBinding.Elements.Add(asbe);
myBinding.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8));
HttpsTransportBindingElement httpsBindingElement = new HttpsTransportBindingElement();
httpsBindingElement.RequireClientCertificate = true;
myBinding.Elements.Add(httpsBindingElement);
return myBinding;
}
When using the binding, I set the ClientCredentials UserName, ServiceCertificate and ClientCertificate, and all works as expected.
Using the code is as follows
using (CredentialingService.SOAPPortTypeClient client = GetCredentialingClient())
{
client.Open();
etc....
}
private static CredentialingService.SOAPPortTypeClient GetCredentialingClient()
{
CredentialingService.SOAPPortTypeClient client = new CredentialingService.SOAPPortTypeClient(GetCustomBinding(), new EndpointAddress(new Uri(Settings.AppSettings.B2BUrl), new DnsEndpointIdentity(Settings.AppSettings.B2BDNSEndpoint), new AddressHeaderCollection()));
client.Endpoint.Contract.ProtectionLevel = System.Net.Security.ProtectionLevel.None;
SetClientCredentialsSecurity(client.ClientCredentials);
return client;
}
where GetCustomBinding is specified in my post
SetClientCredentialsSecurity is where the certificate is set, and is as follows
private static void SetClientCredentialsSecurity(ClientCredentials clientCredentials)
{
clientCredentials.UserName.UserName = Settings.AppSettings.B2BUserName;
clientCredentials.UserName.Password = Settings.AppSettings.B2BPassword;
string directoryName = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
clientCredentials.ServiceCertificate.DefaultCertificate = new X509Certificate2(Path.Combine(directoryName, Settings.AppSettings.B2BServerCertificateName));
clientCredentials.ClientCertificate.Certificate = new X509Certificate2(Path.Combine(directoryName, Settings.AppSettings.B2BClientCertificateName), Settings.AppSettings.B2BClientCertificatePassword);
}
Hopefully that makes it a bit clearer

Maybe it's because your certificate is not publicly valid. Try this:
System.Net.ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(delegate { return true; });
//...
using (var client = new SrvClient())
{
client.ClientCredentials.UserName.UserName = "usr";
client.ClientCredentials.UserName.Password = "psw";
//...
}

Sign SOAP using certificate (WSE)

I have a requirement that I must build a SOAP message and then sign it using an X509 cert before sending it to a service via POST. I have NO idea what type of service this is but I was given a SOAP example.
I tried to use the example on MSDN but it's limited and incomplete and I am not able to instantiate the Security object. But even if I could, how do I associate it with the SoapEnvelope?
http://msdn.microsoft.com/en-us/library/aa529277.aspx
The SOAP message is built via Xslt. I need to get it signed anyway I can. Having a hard time finding anything. any ideas?
I'm currently using the following code to sign the xml and then I inject it into the SOAP xml.
private static XmlElement EncryptMessage(XmlElement msgBody)
{
StoreName storeName = (StoreName)Enum.Parse(typeof(StoreName), "My");
StoreLocation storeLocation = (StoreLocation)Enum.Parse(typeof(StoreLocation), "LocalMachine");
X509Certificate2 cert = X509Helper.GetCertificate(storeName, storeLocation, "CN=Something");
SignedXml signedXml = new SignedXml(msgBody);
signedXml.SignedInfo.CanonicalizationMethod = SignedXml.XmlDsigExcC14NTransformUrl;
signedXml.SigningKey = cert.PrivateKey;
signedXml.KeyInfo.AddClause(new System.Security.Cryptography.Xml.KeyInfoX509Data(cert));
Reference tRef = new Reference("");
XmlDsigExcC14NTransform env = new XmlDsigExcC14NTransform();
tRef.AddTransform(env);
signedXml.AddReference(tRef);
signedXml.ComputeSignature();
XmlElement xmlDsig = signedXml.GetXml();
xmlDsig.SetAttribute("Id", "Signature-1");
return xmlDsig;
}
which returns

Based on what I read here: http://www.trl.ibm.com/projects/xml/soap/wp/wp.html all I need is what I have so I can just inject it into the header.

You don't need WSE, you can sign the message by generating a signature from the body of the message. The code you're using is correct. Just change it to process the body of the message and then put the xml returned by your method int he header of the soap message. Also, it looks like you need to add a reference. The URL should be whatever the ID you gave the body.

I made it in the following way, first take the certificate and keep it in stock certificates, after we access the certificate from the store and sign the soap message
in this link you will find the same example and other similar
http://www.systemdeveloper.info/2013/11/digital-signature-in-c.html
This is an example of how I did it:
public static getDataResponse queryingData(string name)
{
proxy.BanWS conexion = new proxy.Banws();
//VALIDATION OF CONNECTION V3
X509Certificate2 elCert = new X509Certificate2(#"C:\portecle-1.5\12345.P12", "12345");
conexion.ClientCertificates.Add(elCert);
// Copy the certificate to the certificate store using ASPNET
// spent the path and password
X509Certificate2 certificate = new X509Certificate2(#"C:\portecle-1.5\12345.P12", "12345");
X509Store stores = new X509Store(StoreName.My, StoreLocation.CurrentUser);
stores.Open(OpenFlags.ReadWrite);
stores.Add(certificate);
stores.Close();
String sto = X509CertificateStore.MyStore;
// Open the Certificates Stores
X509CertificateStore store = X509CertificateStore.CurrentUserStore(sto);
store.OpenRead();
// We look for the certificate that we will use to perform the signature
String certname = "conticert";
Microsoft.Web.Services2.Security.X509.X509CertificateCollection certcoll = store.FindCertificateBySubjectString(certname);
if (certcoll.Count != 0)
{
Microsoft.Web.Services2.Security.X509.X509Certificate cert = certcoll[0];
SoapContext ctx = conexion.RequestSoapContext;
SecurityToken tok = new X509SecurityToken(cert);
ctx.Security.Timestamp.TtlInSeconds = 120;
ctx.Security.Tokens.Add(tok);
// We signed the request
ctx.Security.Elements.Add(new MessageSignature(tok));
}
//remote call
getDataResponse response = new getDataResponse();
response = conexion.getData(name);
return response;
}
