x509证书签名

使用pfx证书文件，签名怎么做 --------------------编程问答-------------------- using System;
using System.Collections.Generic;

  //生成pfx证书文件
  string MakeCert = "E:\\个人\\usbkey\\iKey1000\\makecert.exe";
  string x509Name = "CN=111";
  string param = " -pe -ss my -n \"" + x509Name + "\" ";
  Process p = Process.Start(MakeCert, param);
  p.WaitForExit();
  p.Close();

  X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
  store.Open(OpenFlags.ReadWrite);
  X509Certificate2Collection storecollection = (X509Certificate2Collection)store.Certificates;
  foreach (X509Certificate2 x509 in storecollection)
  {
  if (x509.Subject == "CN=111")
  {
  Debug.Print(string.Format("certificate name: {0}", x509.Subject));
  byte[] pfxByte = x509.Export(X509ContentType.Pfx, "111");
  FileStream fileStream = new FileStream(Path.Combine("E:\\个人\\usbkey\\iKey1000", "111.pfx"), FileMode.Create);

  // Write the data to the file, byte by byte.
  for (int i = 0; i < pfxByte.Length; i++)
  fileStream.WriteByte(pfxByte[i]);
  // Set the stream position to the beginning of the file.
  fileStream.Seek(0, SeekOrigin.Begin);
  // Read and verify the data.
  for (int i = 0; i < fileStream.Length; i++)
  {
  if (pfxByte[i] != fileStream.ReadByte())
  {
  return;
  }
  }
  fileStream.Close();
  }
  }
  store.Close();
  store = null;
  storecollection = null;
  }
  }
}
如题。

1.需要包含公私钥
2.证书用来加密、解密、签名、验证签名
3.pfx格式（或P12）

这几个是显然满足的
不满足的话能叫pfx的证书么？
但是这个公私钥
是随机产生的
  你使用
X509Certificate2 pc = new X509Certificate2(labelPfxPath.Text.Trim(), textBoxPfxKey.Text.Trim(), X509KeyStorageFlags.Exportable);
使用一个证书文件名、一个用于访问该证书的密码和一个密钥存储标志初始化 X509Certificate2 类的新实例。
你把证书文件名改成证书的目录加文件名就行了

  pc.PublicKey.Key.ToXmlString(false);
  pc.PrivateKey.ToXmlString(true);

X509Certificate2 myX509Certificate2 = new X509Certificate2(@"D:\pdscert\TEST1.pfx", "123456", X509KeyStorageFlags.Exportable);
               str_DataToSign="111
                byte[] DataToSign = Encoding.GetEncoding("GB2312").GetBytes(str_DataToSign);
                RSACryptoServiceProvider provider = (RSACryptoServiceProvider)myX509Certificate2.PrivateKey;
                RSAPKCS1SignatureFormatter RSAFormatter = new RSAPKCS1SignatureFormatter(provider);
                ////Set the hash algorithm to SHA1.
                //RSAFormatter.SetHashAlgorithm("SHA1");
                //SHA1Managed sha1 = new SHA1Managed();
                //byte[] hash = sha1.ComputeHash(DataToSign);
                ////Create a signature for HashValue and return it.
                //byte[] SignedHash = RSAFormatter.CreateSignature(hash);
              // Convert.ToBase64String(SignedHash);
                return Convert.ToBase64String(provider.SignData(DataToSign, new SHA1CryptoServiceProvider()));    --------------------编程问答-------------------- 但以上方法得到的结果值与其他站点接口的验证结果不一致 --------------------编程问答-------------------- 看你需要什么样的签名了
vs 中有 makecert.exe
signcode.exe 等几个文件
你双击打开signcode.exe
按提示就可以对文件签名了
不过你自己生成的pfx 签名没什么用
在网络上还是不安全的 --------------------编程问答-------------------- 我是要用银联提供的证书，http post 提交报文，对银行卡扣款。
就需要对报文进行消息签名呀。
策略当然是提取证书pfx的私钥，对报文进行签名。
应怎么处理呢
