是什么原因导致System.Security.Cryptography.CryptographicException? [英] What could be causing a System.Security.Cryptography.CryptographicException?

问题描述

大家好，

我正在开发一个创建SAML断言，将其转换为XML，然后尝试使用x.509证书对其进行签名的应用.
创建断言后，我创建了一个名为xmlDoc的XML文档.我已经测试了xmlDoc，它是正确的.
我正在使用的证书是:

X509Certificate2 cert = 新 X509Certificate2 (store.Certificates [0]);

Hi All,

I'm working on an app that creates a SAML assertion, converts it to XML, and then attempts to sign it using an x.509 certificate.
After creating the assertion, I create an XML document called xmlDoc. I've tested the xmlDoc, and it is correct.
The cert I'm using is:

X509Certificate2 cert = new X509Certificate2(store.Certificates[0]);

SignedXml sig = 新 SignedXml ();

SignedXml sig = new SignedXml();

System.Security.Cryptography. RSA 键= System.Security.Cryptography. RSA .Create();

sig.SigningKey = key;

System.Security.Cryptography.RSA key = System.Security.Cryptography.RSA.Create();

sig.SigningKey = key;

DataObject dataObject = new DataObject ();

DataObject dataObject = new DataObject();

dataObject.Data = xmlDoc.ChildNodes;

dataObject.Data = xmlDoc.ChildNodes;

sig.AddObject(dataObject);

sig.AddObject(dataObject);

KeyInfo keyInfo = 新 KeyInfo ();

KeyInfo keyInfo = new KeyInfo();

keyInfo.AddClause( 新 RSAKeyValue (键));

keyInfo.AddClause(new RSAKeyValue(key));

sig.KeyInfo = keyInfo;

sig.KeyInfo = keyInfo;

sig.SigningKey = cert.PrivateKey;

sig.SigningKey = cert.PrivateKey;

任何人都可以帮助我弄清楚我做错了什么(或者如果我应该以其他方式对XML签名)?提前非常感谢！

Can anyone help me figure out what I am doing wrong (or if I should be signing the XML in a different way)? Thanks very much in advance!!
