Provide a cryptographic implementation for Qaul.net

The Qaul,net project provides a mesh-wifi network for people to connect and share information to other people on the network, helping them avoid potentially compromised or censored channels of communication. It does however currently do so without any cryptographic layer, exposing potentially personal data to the public in clear text via wireless channels as well as not allow users to verify other users and messages identities. Providing a cryptographic layer for Qaul.net, implementing not only public/ private key method encryption (either via RSA or ECC) but verifiable identities would make Qaul.net a much safer and more private channel of communication for everybody.
