OpenPGP refresh for Conversations
Modernise OpenPGP implementation for Android XMPP client
This project aims to modernize PGP encryption within Conversations, a Jabber/XMPP client, by integrating cryptographic operations and adopting updated messaging standards. Currently, the application relies on a third-party tool, OpenKeychain, which is no longer actively developed and utilizes brittle Inter-process communication (IPC). This work will replace this dependency with the pgpainless library, integrating encryption, decryption, and key management directly into the app to improve reliability and user experience. Furthermore, the project will implement and update the modern OpenPGP standards for XMPP (XEP-0373 and XEP-0374) by making use of Stanza Content Encryption (SCE). This transition not only benefits users who prefer PGP-based encryption but also serves as a critical building block for the development of OMEMOv2.
