Unduh

Klien/server C++ dengan dukungan SSL (TLS/DTLS) (hanya file header)

Tentang

Ini adalah implementasi file header saja dari klien/server C++ dengan atau tanpa SSL/TLS/DTLS. Implementasinya menggunakan OpenSSL dan BSD API untuk mengimplementasikan antarmuka soket yang mendasarinya.

Kompilasi telah diuji dengan:

GCC 11.3.0 (GNU/Linux Ubuntu 22.04.1 LTS)
- buat 3.22.1
- tes google 1.11.0-3
- dentang 14.0.0-1ubuntu1
Komunitas Visual Studio 2022 17.4.4 (64-bit) (Windows 11)
- buat 3.26.0-rc1
- tes google 1.13.0

Penggunaan

Stopkontak

Kelas soket dasar untuk metode kelas API BSD.

 // default constructor - no socket created because type is unknown
Socket ();
Socket::initSocket (domain, type, protocol); // creates socket

// create socket from previously created file descriptor
Socket ( int );

// create socket of the given type - NOTE: This returns a Socket class type that is not a Tcp or Udp socket class
Socket (domain, type, protocol);

Server/klien TCP

Buat objek server TCP untuk menerima koneksi TCP.

 // default no IP/port bound but TCP socket created
TcpServer (); 

// TCP socket created, IP/port bound, but not listening
TcpServer ( const uint16_t port, const std::string& ipAddr = " 0.0.0.0 " );

// TCP socket created, IP/port bound, and listening for clients
TcpServer ( const std::string& ipAddr, const uint16_t port, const int backlog);

Buat objek klien TCP untuk terhubung ke server TCP yang dikenal.

 // default TCP socket created but no server connection
TcpClient ();

// create TcpClient with given TCP socket file descriptor
TcpClient ( const int filedescriptor);

// TcpClient connected to a TcpServer IP/port
TcpClient ( const std::string& ipAddr, const uint16_t port);

Buat Server SSL TCP untuk menerima klien SSL TCP.

 // Create a SSL TCP Server not bound to IP/port
SecureTcpServer ( const std::string& keyFile, const std::string& certFile);

// Create a SSL TCP Server bound to a given port and IP or default IP
SecureTcpServer ( const std::string& keyFile, const std::string& certFile, const uint16_t port, const std::string& ipAddr = " 0.0.0.0 " );

Buat klien SSL TCP untuk menghubungkan ke server SSL TCP.

 // create a SSL TCP client with a given SSL context - used with SecureTcpServer::accept return
SecureTcpClient ( const int filedescriptor, SSL_CTX *sslctx);

// create a SSL TCP client connected to a SSL TCP server
SecureTcpClient ( const std::string& ipAddr, const uint16_t port);

 // Client

// Connect to TCP server on IP 127.0.0.1 and port 54321
TcpClient client ( " 127.0.0.1 " , 54321 );

Server/klien UDP

Buat objek server UDP untuk menerima koneksi UDP.

 // default no IP/port bound but UDP socket created
UdpServer (); 

// UDP server socket created, IP/port bound
UdpServer ( const uint16_t port, const std::string &ipAddr = " 0.0.0.0 " );

Buat objek klien UDP untuk menyambung ke server UDP yang dikenal.

 // default UDP socket created but no server connection
UdpClient ();

// UdpClient connected to a UdpServer IP/port
UdpClient ( const std::string& ipAddr, const uint16_t port) noexcept ( false )

Buat Server UDP SSL untuk menerima klien SSL UDP.

 // Create a SSL UDP Server not bound to IP/port
SecureUdpServer ( const std::string& keyFile, const std::string& certFile);

// Create a SSL UDP Server bound to a given port and IP or default IP
SecureUdpServer ( const std::string& keyFile, const std::string& certFile, const uint16_t port, const std::string& ipAddr = " 0.0.0.0 " );

Buat klien SSL UDP untuk menghubungkan ke server SSL UDP.

 // Create a SSL UDP Client not attempting to connect to a SSL UDP Server (need to call SecureUdpClient::connect(IP, port) to connect)
SecureUdpClient ( const std::string& keyFile, const std::string& certFile);

// create a SSL UDP client connected to a given SSL UDP server waiting in a SecureUdpServer::accept call on the given IP and port
SecureUdpClient ( const std::string& ipAddr, const uint16_t port, const std::string& keyFile, const std::string& certFile);
