SignedXml CanonicalizationMethod - http://www.w3.org/2006/12/xml-c14n11

Question

是否可以使用带有SignedXml的http://www.w3.org/2006/12/xml-c14n11 CanonicalizationMethod？

SignedXml signedXml = new SignedXml(xmlDoc);
signedXml.SignedInfo.CanonicalizationMethod = "http://www.w3.org/2006/12/xml-c14n11";

扔了

System.Security.Cryptography.CryptographicException: Could not create the XML tr
ansformation identified by the URI http://www.w3.org/2006/12/xml-c14n11.

谢谢!

看起来.NET 还没有实现它。

您可能必须像这样创建自己的 Transform 类：

public class XmlDsigC14N11Transform: XmlDsigC14NTransform
    {
        public override void LoadInput(object obj)
        {
            //do something here
            base.LoadInput(obj);
        }

        public override object GetOutput()
        {
            //do something here
            return base.GetOutput();
        }
    }

并将您的转换映射到“ http://www.w3.org/2006/12/xml-c14n11 ”。

CryptoConfig.AddAlgorithm(typeof(XmlDsigC14N11Transform), "http://www.w3.org/2006/12/xml-c14n11");
