在使用C#的WebRequests时解密Wireshark中的TLS通信,可以通过以下步骤实现:
using Org.BouncyCastle.Crypto.Tls;
using Org.BouncyCastle.Security;
using System.IO;
using System.Net;
public class TlsDecryptor : DefaultTlsClient
{
private readonly AsymmetricKeyParameter privateKey;
public TlsDecryptor(AsymmetricKeyParameter privateKey)
{
this.privateKey = privateKey;
}
public override TlsAuthentication GetAuthentication()
{
return new AlwaysValidTlsAuthentication();
}
public override TlsEncryptionCredentials GetEncryptionCredentials()
{
return new DefaultTlsEncryptionCredentials(Context, new[] { privateKey });
}
}
public class AlwaysValidTlsAuthentication : TlsAuthentication
{
public TlsCredentials GetClientCredentials(CertificateRequest certificateRequest)
{
return null;
}
public void NotifyServerCertificate(Certificate serverCertificate)
{
// Always accept the server certificate
}
}
public class Program
{
public static void Main()
{
// Load the server's private key and certificate
AsymmetricKeyParameter privateKey = // Load the private key from file
Certificate certificate = // Load the certificate from file
// Create the TLS decryptor
TlsDecryptor tlsDecryptor = new TlsDecryptor(privateKey);
// Create the web request
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://example.com");
// Set the TLS decryptor as the SSL/TLS client
ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
ServicePointManager.Expect100Continue = true;
request.ClientCertificates.Add(new X509Certificate2(certificate.GetEncoded()));
// Make the web request
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
// Read the response
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
string responseText = reader.ReadToEnd();
// Process the decrypted response
}
}
}
}
在上面的示例代码中,你需要替换以下部分:
privateKey
:加载服务器的私钥文件,并将其转换为AsymmetricKeyParameter
对象。certificate
:加载服务器的证书文件,并将其转换为Certificate
对象。https://example.com
:替换为你要访问的TLS加密网站的URL。请注意,这只是一个简单的示例代码,实际应用中可能需要根据具体情况进行调整和优化。
