I’m looking for an open source self-hosted chat system.
Here are my specs:
- it should support end-to-end encryption, preferably with AES-256 support
- it should be secure and avoid any homemade encryption protocol
- it should be user-friendly
- it should be available both for the web (and mobile), Android and preferably iOS and the phone
- it should preferably be open source and/or self-hosted
