All traffic between clients was encrypted by Tor's built-in mechanisms, ensuring that messages remained confidential and that it was difficult for any third party to determine who was communicating with whom or the physical location of any participant. The end-to-end encryption was provided by the Tor hidden service itself, which uses the Tor protocol's layered encryption to protect data as it traverses the network.

They connect at a mutually agreed-upon, randomized intermediate "Rendezvous Point". All traffic between clients was encrypted by Tor's
The Tor network retains hidden services only as long as the host machine keeps generating the key and running Tor. Since TorChat has been dead for a decade, it is that a TorChat hidden service is still active at that address. Because development on the original TorChat ecosystem has
Because development on the original TorChat ecosystem has largely ceased, privacy advocates and developers have shifted toward actively maintained open-source alternatives. Modern applications like , Cwtch , and Speek utilize updated protocols to handle decentralized, serverless communication safely over modern Tor infrastructure.
