What is DinoX?

DinoX is a modern XMPP (Jabber) messaging client for Linux built with GTK4 and libadwaita.

DinoX features System Tray support, MUJI group video calls, voice messages, message retraction, advanced MUC moderation and more.

Key Features

Feature	Description
Encrypted File Upload	AES-GCM URI Scheme & XEP-0448 support for secure file sharing
Full Local Encryption	All local files (avatars, stickers, transfers) are encrypted at rest (AES-256-GCM)
Secure Deletion	Global history deletion (both sides) with smart throttling & zero-trace cache cleanup
OMEMO Encryption	End-to-end encryption for all messages and files
OpenPGP Encryption	XEP-0373 with key management, generation & deletion
Encrypted Local Database	Local data is stored in an encrypted SQLCipher database (password required at startup)
Change Database Password	Change the local database password via Preferences (SQLCipher rekey)
Panic Wipe	Quickly wipe local DinoX data (Ctrl+Shift+Alt+P) and exit (also triggered after 3 failed unlock attempts)
OpenPGP Keyring Isolation	Uses an app-scoped GNUPGHOME so Panic Wipe removes OpenPGP material

Local data encryption

DinoX stores your local data (accounts, messages, settings, cached metadata) in an encrypted SQLCipher database.

• You will be prompted for a password on startup.
• If you forget the password, the database cannot be recovered.
• A Panic Wipe action is available via the app menu and the shortcut Ctrl+Shift+Alt+P.

Audio/Video calling notes

DinoX 1:1 calling focuses on cross-client interoperability (notably with Conversations (Android) and Monal (iOS)) while keeping the existing media stack:

• Media stack: GStreamer (RTP/rtpbin + WebRTC elements), libnice (ICE), gnutls (DTLS), libsrtp2 (SRTP).
• Security profile: DTLS-SRTP only (no SDES-SRTP).
• Baseline codecs: Opus (audio) and VP8 (video) for reliable interop.
• Optional audio quality: webrtc-audio-processing enables AEC/NS/AGC if present.

  Note: Many distributions ship outdated versions. For best quality (Echo Cancellation), we strongly recommend building version 2.1+ from source. See BUILD.md.

If you are building from source using distro packages, ensure you are on a sufficiently new libnice (recommended: >= 0.1.23). For collecting reproducible call logs, see DEBUG.md.
