1. Pc-client.crt

2. Pc-client.key

3. Pc-server.pem

These 3 key files are generated by the server, in this machine with the P12 file generation, do not know what reason can not be certified successful, perhaps because it will not use OpenSSL, the full solution of the great God.

About the HTTPS authentication process, self-Baidu bar. The Qnetwork class is also good for encapsulation, both asynchronously and with the parsing of the JSON string.
