OnionPhone (OPH) is a VOIP tool for calling over Tor network which can be used as a VOIP plugin for TorChat. Call is targeted to the onion address of the recipient (its hidden service HS).
OPH provides independent level of p2p encryption and authentication which employs modern cryptographic primitives: Diffe-Hellmann key exchange on Elliptic Curve 25519 and Keccak Sponge Duplexing encryption. In the case of a call to the onion address Tor protects against MitM attacks. Also the recipient can verify identity of the originator’s onion address (only with the permission of the sender) similarly to the TorChat authentication.
