According to Whonix’s wiki, Tor Messenger has been deprecated and should therefore no longer be used with Whonix. On the same page, no XMPP client is suggested.
Is there any way (running a chat client from a stick?, for example) that XMPP could be used through Whonix or Qubes in a safe way? Yes, it is not decentralized, but that doesn’t mean Whonix isn’t safe since of course the servers that hold the XMPP communications have nothing to do with Whonix.
I’d also like to know, if anyone is willing to share, what chat client would be safest to use via Whonix and Qubes? The same Whonix wiki suggests CoyIM, but in the comments therein people criticize it as not being up to the job. I’d like to use XMPP but also to have an alternative that is not centralized. Tox is nice but then it doesn’t really do much in the way of obfuscating one’s IP. If it’s through Whonix that problem is of course solved but still. Ricochet IM I’ve never tried but apparently, like Tox, it’s another P2P. Not sure if wireshark would help identify IP addresses.
Anyways, the most important for now, at least for me, is figuring out an XMPP client that works in Whonix and that is as safe as any other XMPP client.
Thank you for reading and for any help you might offer!!
