TORCHAT DEBIAN FULL

Onion Phone provides Perfect Forward Secrecy (uses a fresh key for each call) and Full Deniability for using long-term public keys of participants (as a fact and a content of the conversation): like a deniable SKEME protocol uses for initial key exchange.

using a long-term public keys signed by PGP.

using previously shared password (with the possibility of hidden notification under enforcement).

Other possible ways of multifactor authentication are: Also the recipient can verify identity of the originator's Onion address (only with the permission of the sender) similarly to the TorChat authentication. In the case of a call to the Onion address Tor protects against MitM attacks. OnionPhone provides independent level of p2p encryption and authentication that uses modern cryptographic primitives: Diffie-Hellmann key exchange with Elliptic Curve 25519 and Keccak Sponge Duplexing encryption. OnionPhone uses a custom UDP/TCP protocol (not RTP) with only one byte unencrypted header that can provide some obfuscation against DPI. In addition, OnionPhone can establish a direct UDP or TCP connection to the specified port on IP-address or host.

The ability to switch to a direct UDP connection (with NAT traversal) after the connection is established over Tor ( Tor instead of SIP without a specialized server, any registration or metadata collection) is also provided. The recipient can initialize a reverse Onion connection to the originator's HS and use a faster channel periodically resetting the slower channel to reduce overall latency.

Call is targeted by the Onion address of the recipient (its hidden service HS). OnionPhone is a VOIP tool for calling over Tor networ which can be used as a VOIP plugin for TorChat.
