How to display received information in openssl?

Question

OpenSSL

There is a need to output all data received and sent by openssl.
I run Openssl locally under ubuntu, to debug my program, I need to see what openssl received and sent.
Is it possible to download openssl with the output of information received and transmitted?
If you need to install a patch, then help with finding it. I didn't find it myself.

Answer 1

the question is somewhat incomprehensible - is your application linked with openssl libraries? do you need to watch the ssl handshake or the data in the lifted session?
traffic can be viewed through wireshark, if you need to watch inside the session, then SSL_set_msg_callback/SSL_set_msg_callback_arg and SSL_set_tlsext_debug_callback/SSL_set_tlsext_debug_arg.
