Answer 4

As far as I know, any jabber client + OTR , well, up to a bunch of PGP.
After 10 seconds of going to Google - Xabber. If everything is very secret, then your own floating jabber server. I didn’t use telegram, but I condemn it, since a large company always has decryption tools, they have their own algorithms, which they can easily decrypt. Means should be selected individually for each situation, so to speak. Encryption from the provider, corporate parties and so on.
