## Client TLS Tutorial

### client-tls.c

Again, we will need to import the security library.  Just like in the server, add an '#include' statement in your client program.  Next we will need to add a global 'cert' variable: 
'''c
const char* cert = "./certs/ca-cert.pem";
'''
Now comes changing the 'ClientGreet()' function so its arguments and functions incorporate the security library.
'''c
void ClientGreet(int sock, CYASSL* ssl)

if (CyaSSL_write(ssl, send, strlen(send)) != strlen(send)) {

if (CyaSSL_read(ssl, receive, MAXDATASIZE) == 0) {
'''
You can think of this as, instead of just a normal read and write, it is now a “secure” read and write.  We also need to change the call to 'ClientGreet()' in 'main()'.  Instead of calling directly to it, we should make a call to a 'Security()' that will then check the server for the correct 'certs'.  To do this, change:
'''c
ClientGreet(sock(fd));
'''
to
'''c
Security(sockfd);
'''
Now we just have to make the 'Security()'
