“Off-the-Record Messaging, commonly referred to as OTR, is a cryptographic protocol that provides strong encryption for instant messaging conversations. OTR uses a combination of the AES symmetric-key algorithm, the Diffie–Hellman key exchange, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption.
The primary motivation behind the protocol was providing deniability for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.”
A mesh network is a decentralized peer-to-peer network, with user-controlled physical links that are usually wireless.
“Mesh networking (topology) is a type of networking where each node must not only capture and disseminate its own data, but also serve as a relay for other nodes, that is, it must collaborate to propagate the data in the network.“

Use a combination of Tor Browser and a free web browser of your choice to the surf the web.
Try to use Tor Browser as often as possible. Browsing is slower with Tor, but far more secure.

There is also a DuckDuckGo hidden service at 3g2upl4pq6kufc4m.onion for Tor users.
