xml-dsig

I've got an X509Certificate2 containing a public key. I've got an RSACryptoServiceProvider (which came from calling SignedXml.CheckSignatureReturningKey ), also containing a public key. I want to find out if one came from the other. How can I compare the two? You can compare the PublicKey property of signing certificates in the SignedXml.KeyIfo with signing key output from SignedXml.CheckSignatureReturningKey . This C# extension method does the job for me: public static bool CheckSignatureReturningCertificate(this SignedXml signedXml, out X509Certificate2 signingCertificate) {

I am trying to do some XML Signature by signing only parts of the xml however after much searching I have not been able to find a solution. I am using java to sign an XML using Xpath2 transform and EXCLUSIVE canonicalization. If I have the following XML <?xml version="1.0" encoding="UTF-8"?> <msg xmlns="http://someaddress/ad/m1" xmlns:ns1="http://someotheraddres/ad/m2" xmlns:ns2="http://www.w3.org/2000/09/xmldsig#"> <header> <id>wsfrwerwerwer</id> <name>addr</name> <somenode> <trace>ND</trace> </somenode> </header> <payload><ns0:addr xmlns:ns0="http://someaddres/ad/m3"><ns2:data xmlns:ns2=

I'm using XMLDSIG to sign a configuration file . I'd like my CA to be able to issue keys that can be used to sign XML. I'd then like to verify that the XML was signed with a key issued by my CA. How do I get the signing certificate out of the SignedXml object? How do I follow the certificate chain back to a specific CA? Note that the public key for my CA will be stored in my executable, rather than the certificate store. Roger Lipscombe To attach arbitrary certificates to an XML-DSIG file, add an <X509Data> element . To do this in .NET, use: signedXml.KeyInfo.AddClause( new KeyInfoX509Data

Is it possible to create jaxb marshaller which automatically adds digital signature to xml content. For example if I have a class which is defined: @XmlRootElement @XmlAccessorType(XmlAccessType.FIELD) public class Test { @XmlElement private String info; public String getInfo() { return info; } public void setInfo(String info) { this.info = info; } } And my xml which is produced by marshaller looks like: <?xml version="1.0" encoding="UTF-8" standalone="yes"?><test><info>value</info></test> And I expect it to look like: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Security>
