Compile

cmake CMakeLists.txt

make all

Run

./TlsServer

Example

#include <iostream>
#include <string>

#include "TlsServer.h"
#include "NetworkException.h"

using namespace stream;

int main() {
    char buff[1024];
    std::string str = "Hello there!";

    std::cout << "TLS server begin ..." << std::endl;

    TlsServer tls(8080);

    try {
        if (tls.configureContext("/path/to/certificate.pem", "/path/to/key.pem") == -1) {
            throw NetworkException("configure context error, check certificate and key ...");
        }

        if (tls.tlsAccept() == -1) {
            throw NetworkException("accept error");
        }

        while (1) {
            int bytesReceived = tls.tlsReceive(buff, sizeof buff);

            if (bytesReceived == 0) { /* Client closed connection */
                std::cout << "client closed connection" << std::endl; // Hello
                tls.shutdownSsl();
                break;

            } else if (bytesReceived == -1) {
                tls.shutdownSsl();
                throw NetworkException("receive error");

            } else {

                }
            }
        }

    } catch (NetworkException& ex) {
