Plugging end-to-end encryption in Posca

End-to-end encrypted communication client

Posca is a self-hosted, end-to-end encrypted communication client built on the Matrix protocol, combining chat, forums, microblogging, and media sharing in a single interface. Posca relies exclusively on the standard client-server API, making it easy to use with any homeserver. It is made to interoperate with other Matrix clients and the wider federated Web. It is designed for communities and collectives of all sizes, from civil society organisations and labour movements to citizen assemblies and hackerspaces, to communicate and organise outside of corporate, surveillance-based platforms.
