I am analysing a programm with frida that definitely connects to some server via SSL. When I call SSL_get_fd, it returns -1. From the documentation I see that this means that ssl doesnt wrap a socket (BIO is definitely configured, as I can access it via SSL_get_rbio). How can openssl connect to a server without a socket? Is there any way to see the peer address/port without accessing the underlying socket?
What does it mean, when SSL_get_fd returns -1?
