Re: How to change mode from Blocking to Non-blocking

This has nothing to do with openssl in particular. This is a general socket programming scenario. You can set your socket to non-blocking mode using fcntl(socket, F_SETFL, O_NONBLOCK) / ioctlsocket(AcceptSocket, FIONBIO, NonBlock) Google or RTFM if you wish to know more about these functions.

Re: RSA and DH

As per my understanding, using public key cryptography for encryption is much more expensive than using symmetric key cryptography. So generally the main communication is encrypted using symmetric key cryptography, whereas public key cryptography is used to exchange keys and other information
