I'd be curious to hear HN's thoughts on what messaging apps they use/trust.

I've tried in the past to get friends to switch over to Telegram, but there are issues since they rolled their own encyption protocol.

I've looked into using Mumble for voice, it seems quite secure because you host it yourself, and it's open source.

There's also a good list from the EFF: https://www.eff.org/node/82654
