With this tag, the verification of certificates can be controlled:
0: no verify certificates.
1: on server mode, the certificate returned by client is checked and
   if fail the TLS/SSL handshake is immediately terminated.
1: on client mode, the server certificate is verified and
   if fail the TLS/SSL handshake is immediately terminated.

I added this tag, because I'd like that my application not connected to a
server with a untrusted certificate.
