RSA加密加密Xml文件转换成byte [] [英] Error with RSA Encrypting Xml file converted into byte[]
问题描述
这是后续的此SO文章,我学会了生成RSA密钥对并将公钥存储在设置中。我通过以下方式生成了我的密钥:
This is a follow-on to this SO post in which I learned to generate the RSA key pair and store the Public key in the Settings. I generated my key by:
CspParameters cspParams = new CspParameters();
cspParams.KeyContainerName = "XML_ENC_RSA_KEY";
RSACryptoServiceProvider rsaKey = new RSACryptoServiceProvider(cspParams);
string keyXml = rsaKey.ToXmlString(true);
我将该字符串的公钥部分复制到我的程序设置中,看起来像:
I copied the public key part of that string into my program settings and it looks like:
"<RSAKeyValue><Modulus>mfXS3Na0XfkjhpjS3sL5XcC9o+j6KXi1LB9yBc4SsTMo1Yk/pFsXr74gNj4aRxKB45+hZH/lSo933NCDEh25du1iMsaH4TGQNkCqi+HDLQjOrdXMMNmaQrLXGlY7UCCfFUnkEUxX51AlyVLzqLycaAt6zm5ljnDXojMC7JoCrTM=</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>"
看起来有效吗?
然后我正在使用我的XML文档,并尝试将其转换为Encrypt函数的字节[]:
Then I am taking my XML document and trying to convert it to a byte[] for the Encrypt function:
string fileName = System.IO.Path.Combine(Application.StartupPath, "alphaService.xml");
XDocument doc = new XDocument();
XElement xml = new XElement("Info",
new XElement("DatabaseServerName", txtServerName.Text),
new XElement("DatabaseUserName", txtDatabaseUserName.Text),
new XElement("DatabasePassword", txtDatabasePassword.Text),
new XElement("ServiceAccount", txtAccount.Text),
new XElement("ServicePassword", txtServicePassword.Text),
new XElement("RegistrationCode", txtRegistrationCode.Text));
doc.Add(xml);
doc.Save(fileName);
// Convert XML doc to byte stream
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fileName);
byte[] fileBytes = Encoding.Default.GetBytes(xmlDoc.OuterXml);
Encrypt(fileBytes);
我正在从Encrypt函数获取一个Syntax Error line1,即:
I am getting a "Syntax Error line1" from the Encrypt function which is:
private static byte[] Encrypt(byte[] bytes)
{
using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider())
{
rsa.FromXmlString(Properties.Settings.Default.PublicKeyXml);
return rsa.Encrypt(bytes, true);
}
}
任何想法?编辑:实际的错误是:
Any ideas? The actual error is:
rsa.FromXmlString(Properties.Settings.Default.PublicKeyXml);
推荐答案
我只是在看你的帖子寻找信息在RSACryptoServiceProvider上。我试过你的代码,它为我工作,那么,我从来没有收到你所做的错误,直到我再次阅读你的消息。
I was just looking at your post here looking for information on the RSACryptoServiceProvider. I tried your code and it worked for me, Well, sort of, I never got the error you did until I started reading your message again.
从Properties.Settings中的公钥中删除引号。当我看到你发布的公钥时,我进去并将引号添加到我的字符串,我得到完全相同的错误。
Remove the quotes from your public key in the Properties.Settings. When I saw what you had posted for your public key I went in and added the quotes to my string and I get the exact same error you did.
一个错误,但不同于你的加密是错误的长度错误。但是,我发现,如果我将XmL转换为一个字节到.ToString()而不是.OuterXML它是有效的。
Where I did get an error but different from yours was getting a bad length error on the encrypt. However, I figured out that if I change the line for converting the XmL to a byte to .ToString() and not .OuterXML it works.
private void button4_Click(object sender, EventArgs e)
{
string fileName = System.IO.Path.Combine(Application.StartupPath, "alphaService.xml");
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fileName);
byte[] fileBytes = Encoding.ASCII.GetBytes(xmlDoc.ToString());
byte[] EncryptedBytes = Encrypt(fileBytes);
string EncryptedString = Encoding.ASCII.GetString(EncryptedBytes);
}
private static byte[] Encrypt(byte[] bytes)
{
using (RSACryptoServiceProvider rsa = new RSACryptoServiceProvider())
{
rsa.FromXmlString(Properties.Settings.Default.PublicKeyXml);
return rsa.Encrypt(bytes, false);
}
}
我将其改为ASCII码,因此我可以转换字节数组到一个字符串,最好是使用相同的方法转换为字节数组。
I changed and encoding to ASCII so I could convert the byte array to a string and it's better to do that if you convert to the byte array using the same method.
