xml-signature

I've looked at other posts on here regarding this issue and none of them seem to address my situation. I've been trying to verify a SAML assertion for the last week and I have 2 clients that have sent me SAML but I cannot verify it. The main process is we get a base64 encoded assertion and I decode it. Load it into an XmlDocment with PreserveWhitespace = true. The verify method is public static bool Verify(X509Certificate2 cert, XmlElement xmlElement, SignedXml signedXml) { bool flag; try { KeyInfo keyInfo = new KeyInfo(); var clause = new KeyInfoX509Data(cert); keyInfo.AddClause(clause);

I have a HTML page(A Form) where user will enter his details. Details to enter are Name age salary state City Now when user enters all details and click Button then I will create xml file containing the user details like <root> <name>abc</name> <age>40</age> <salary>20000</age> <state>xyz</state> <city>abc</city> </root> After this I want to sign this xml file using XMLSignature . I want to sign only two elements of document i.e name and salary element using XSLT transform and some digest and signature method. My question is how to use the XSLT transform in our xmlsignature's transform element

I'm receiving a SAML request via HTTP-redirect binding the content of the SAML request look like this {"SigAlg"=>" http://www.w3.org/2000/09/xmldsig#rsa-sha1 ", "SAMLRequest"=>"lVLLaoQwFP0VyT5jEqPG4AiFoSDMtNApXXQzxDxaQRObRDqfX3XoolAKXd7DPQ/uuXUQ4zDxo3tzc3zSH7MOMWkPe3DpcixzVVVQl4RBqoiCncEYEmkoY7k00hCQvGgfemf3gOwQSNoQZt3aEIWNC4RwCRGGiD6jkmPMs2KHUPYKksPi0lsRN+Z7jFPgafqpvejtbtQpSK7jYAPfsu3B7C13IvSBWzHqwKPk57vTkS+WfPIuOukG0NSbub9R/yaJELRfzUGzrhmtFut15qdeeheciY926K2u05toUz8sIu0huXd+FPFv9RXpFTTbKp/WA4WobQT/jEYrykwhNaQ66yDNMwY7wijEtMCmysqqo6xOb8Ga+tbjWYe1jtYqfW0uCucoYwWCHS3F0kRGoajWTpAiiJRZJRmu01+Y3

Problem: I am using OpenSAML to build a means of authenticating the SAML 2.0 response posted to our servers. I have got most of it working, with the ability to access the various aspects of the assertion. The only issue is that when I attempt to validate the signature using the public key below, it states that " Signature did not validate against the credential's key ". Any ideas?

I apologize in advance for the rather lengthy block of code, but it's the smallest compilable example I could produce. I already omitted all error checking from the original code. I'm using Visual Studio 2012 and .NET 4.5, although this is nothing new to 4.5, it should work with any version. I am trying to sign an XML documents' elements to protect them from tampering. I don't want to protect the whole document, but only certain elements. Maybe even different elements with different keys. However, when I sign three example elements and try to verify them, the first one always verifies, the

I realise this question may be a bit vague or I may be using incorrect terminology, that is because I am trying to get to grips with this stuff :). I have a requirement to implement digital signing of a XML message by using a dsig:Signature section. I think I understand this process; I will use a private key to sign it which will guarantee to the recipient that it was me who sent the message and that no one has tampered with it. Am I right that this is different from implementing TLS Client Certificates but the goal is the same? (because TLS is transport level, right?) Would implementing
