Hi all, I am newbie to openssl any help is greatly appreciated. I have a requirement of fetching the Common name (domin name ) from the certificate that I request from any HTTPS websites. I followed the regular method of
1. establish a connection with the ip address using *connect() *system call. 2. Use *SSL_connect()* system call to perform handshake. 3. Use *SSL_get_peer_certificate()* to get the certificate. The problem I faced was that, the connect() call would at times return a errno 4 (EINTR) error . So i changed code from blocking to non-blocking sockets and used select() call to have a valid connection and return an appropriate file descriptor. Now the ssl_connect() call returns SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE error. I am unable to make my code work by adding a select() even on ssl_connect() call. If any one can please help as to how I need to use the ssl_connect() by polling that would be of great help. preferred language would be C/C++ thanks, ~Arjun
