Hello, 1 - Ring is a distributed communication platform with no sort of central server. The OpenDHT network is used as a discovery service. bootstrap.ring.cx is used as a configurable publicly known entry point to the network (it can be the address of any running OpenDHT node).
2- After discovery, SIP communications happen on a peer-to-peer TLS (DTLS 1.2) connection (with media on SRTP). Public key fingerprints are known beforehand : it's the Ring ID, but full certificate exchange and key negotiation happens during the TLS handshake. TLS connection uses forward-secure ciphers to provide communication forward secrecy, typically ECDHE-RSA-AES-256-GCM. 3- As mere public key fingerprints, Ring IDs can't be taken down, and can be generated at will. You can report issues on our Tuleap: https://tuleap.ring.cx Code is hosted on Gerrit: https://gerrit-ring.savoirfairelinux.com Best regards, Adrien From: "Mars" <darknessx....@gmail.com> To: Ring@lists.savoirfairelinux.net Sent: Friday, August 19, 2016 9:03:21 AM Subject: [Ring] Questions from a newbie :) Hello, I hope you don't mind me asking a lot of questions: 1- I don't get which part is decentralized; is there a discovery server of some sort or is it this where OpenDHT is used? (Just need a conformation :) 2- The communication and key exchange, where do they take place? Directly between participating clients? What crypto ciphers are used here (not protocols, i.e. SRTP)? Can participating parties verify the security of the communication channel after they've established it? 3- I also see that there's a Ring ID, where does that come from? Is there anyway a Ring ID can be censored or taken down by any higher authority (like Ring developers)? META: Is there a GitHub/GitLab/BitBucket or similar page for this project? _______________________________________________ Ring mailing list Ring@lists.savoirfairelinux.net https://lists.savoirfairelinux.net/mailman/listinfo/ring
