End-to-end encryption has become a basic feature of messaging apps. WhatsApp was banned from China after implementing it. So, is there any end-to-end encrypted chat app which is usable right now in China (PRC)?
- End-to-end encryption (preferably audited, not just claimed)
- Runs on Android and iOS
- Reliably usable within People's Republic of China without a VPN
- Available in English and Chinese
- Reasonably user-friendly (novices can set it up and use it without external help)
Using a normal messaging app combined with an encryption+obfuscation tool would work, but please only propose such a solution if it is provides a user-friendly interface that hides the encryption and copy/pasting steps, and only shows messages.
