How to Protect Your Network with RSA Keys

    A peer can authenticate itself towards a network with its RSA key, which can be managed from the client interface. The authentication status of peers is trusted (auto) by default. This means that peers can interact with each other since the client automatically authenticates and trusts the connecting peer.

    You can manually authenticate peers by blocking new network members from establishing connection to your client.

    Note: This functionality is not available on Linux.
    1. Go to the System > Preferences > Security tab.
    2. Choose the Block new network members by default option.

      Result: The status of a blocked network member becomes unverified.

    3. Authenticate the peer, for example by asking him to send you his public RSA key.
      Chatting with untrusted peers is possible in Hamachi, but you cannot establish a network connection to them.
    4. Right-click on the name of the peer and select Trust > Trusted.
