有没有办法使用FtpWebRequest在C＃中使用客户端证书进行FTP验证？ [英] Is there a way to use FtpWebRequest to authenticate to FTP using client certificates in C#?

问题描述

我试图上传文件到FTP服务器，我需要使用客户端证书进行身份验证，而不是用户名和密码。

I am trying upload a file to a FTP server and I need to use client certificate to authenticate and not the username and password.

var fullFtpPath = String.Concat(ftpItem.FtpAddress, "/", record, ".txt");

FtpWebRequest request = (FtpWebRequest) WebRequest.Create(fullFtpPath);
request.Credentials = new NetworkCredential(ftpItem.Username, ftpItem.Password);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.UseBinary = true;
request.UsePassive = ftpItem.UsePassive;
request.EnableSsl = ftpItem.UseSSL;

request.ContentLength = bytes.Length;
using(Stream s = request.GetRequestStream()) {
    s.Write(bytes, 0, bytes.Length);
}

FtpWebResponse response = (FtpWebResponse) request.GetResponse();
Debug.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

db.LogExport(siteId, fullFtpPath, record, true, response.StatusDescription);
response.Close();

以上是我目前的代码，但我不确定如何实施证书认证，或者如果它是甚至可以做到这一点。我必须创建证书吗？或者服务器会为我提供一个证书，我只是将它设置在我的请求中？

Above is my current code, but I am not sure how to implement the certificate authentication or if it is even possible to do it. Do I have to create the certificate? Or the server will provide me a certificate and I will just set it in my request?

推荐答案

• 使用 FtpWebRequest.ClientCertificates 属性指定要用于身份验证的证书
  
• 证书的格式为 type X509Certificate


• 您可以自行构建证书（来自字节数组或从文件导入），或者在证书存储中查看证书（





• Use FtpWebRequest.ClientCertificates property to specify certificate to use for authentication
• The certificate is of type X509Certificate
• You either construct the certificate on your own (from byte array or import from a file), or look it up in a certificate store (X509Store)

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com");

request.Credentials = new NetworkCredential("username", "");

// Query certificate from store
X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly);
const string tp = "2b6f8ac51a85cbaf429474a55304313968667611";
X509Certificate2 cert2 =
    store.Certificates.Find(X509FindType.FindByThumbprint, tp, true)[0];
store.Close();

// Add certificate into request
request.ClientCertificates.Add(cert2);
