It sounds reasonable? If anything this highlights the problem with all the new encrypted communications options, even highly technical people can&#x27;t really know how good it is from a cursory look. Just because it says end to end encryption and uses some nice ciphers it doesn&#x27;t mean the implementation is not critically flawed.<p>I use Signal right now (from Moxie Marlinspike&#x2F;Whisper Systems) and would only really consider alternatives if they were endorsed by other cryptographers I know because I really just don&#x27;t have a strong enough grasp of how all the machinery interacts.
