c# - 加密文件并通过

Question

我需要使用 AES 192 加密文件并通过套接字将其发送到客户端。我正在使用此代码来加密文件:

string outputFile = "crypted";

            //Confidentiality
            RijndaelManaged AES192Confidentiality = new RijndaelManaged();
            AES192Confidentiality.KeySize = 192;
            AES192Confidentiality.BlockSize = 192;
            AES192Confidentiality.IV = ConfIV;
            AES192Confidentiality.Key = ConfKey;
            AES192Confidentiality.Mode = CipherMode.CBC;
            FileStream inputFileStream = new FileStream(par.GetFilePath(), FileMode.Open, FileAccess.Read);
            FileStream outputFileStream = new FileStream(outputFile, FileMode.Create, FileAccess.Write);
            byte[] inputFileData = new byte[(int)inputFileStream.Length];
            inputFileStream.Read(inputFileData, 0, (int)inputFileStream.Length);
            CryptoStream encryptStream = new CryptoStream(outputFileStream, AES192Confidentiality.CreateEncryptor(), CryptoStreamMode.Write);
            encryptStream.Write(inputFileData, 0, (int)inputFileStream.Length);
            encryptStream.FlushFinalBlock();
            encryptStream.Close();

我想知道我现在如何通过套接字发送这个加密的临时文件，以便接收方可以重建文件并解密它。有人可以给我一些教程或指南吗？提前谢谢大家

您可以创建 NetworkStream 的实例获取套接字，然后调用 encryptStream.CopyTo(myNetworkStream);
