XML signature verification library in C?

Question

Are there any available libraries in C language to verify XML signatures? I could only find one library for C++ from http://santuario.apache.org/cindex.html .

Answer 1

Here's one: XML Security Library (xmlsec) is a C library based on LibXML2

Answer 2

Besides the Apache XML Security suite, and XMLSec, you might check Microsoft's DCOM-based XML Signature implementation. For the Win7 web services stack, there is certainly also an XML Signature implementation but it seems not to be publicly exposed in the API.

Answer 3

System.Security.Cryptography.Xml

SignedXml sx = new SignedXml((XmlElement)responseDocument.GetElementsByTagName("tns:CreateCertificateResponse")[0]); XmlNodeList nodeList = responseDocument.GetElementsByTagName("Signature"); foreach (XmlElement element in nodeList) { // Load the signature node. sx.LoadXml(element); sx.CheckSignature(bankSigningCertificate, true); }

This is how you can verify signature in c#. Use this library "System.Security.Cryptography.Xml"
