'STARTTLS' like connection

[dreamy]

Hello,

this is my first post on this forum and i am totally new in POCO C++ libraries, so judge me gently.

I was able to build a simple TCP-based server application and I'd like to implement optional TLS connection by issuing a command during insecure connection (I'd also like to "escape" from this secured connection back to insecure if possible).
I believe I'd like same behavior as STARTTLS command in SMTP... Is (and if yes, then how) this possible in POCO?

I see a few replies in newer threads, but none in this. Does it mean that no solution exists?

I'm feeling really ignored.

See the implmenentation of Poco::Net::SecureSMTPClientSession in the NetSSL_OpenSSL library, specifically the startTLS() method:

Code: Select all

bool SecureSMTPClientSession::startTLS(Context::Ptr pContext)
{
   int status = 0;
   std::string response;
   
   status = sendCommand("STARTTLS", response);
   if (!isPositiveCompletion(status)) return false;

   SecureStreamSocket sss(SecureStreamSocket::attach(socket(), pContext));
   socket() = sss;
   
   return true;
}

So I can attach an opened socket to a new SecureStreamSocket anytime? That looks really simple, thank you really really much.
