Noghteha

A Decentralized Messaging Platform Engineered for Resilience and Privacy

Noghteha is a mesh networking messenger that redefines communication by maintaining functionality where traditional internet-dependent apps fail. It establishes a robust, local peer-to-peer network using Bluetooth and Wi-Fi Aware technology, enabling messages to hop silently between devices without cellular data or Wi-Fi access. This architecture is designed for scenarios ranging from dense gatherings and remote travel to emergency preparedness, ensuring continuous contact. For global reach, an integrated online mode routes traffic through the Tor network and the Nostr protocol, providing a seamless transition between offline and private online communication without altering the user's workflow.

Core Technical Operation and Offline Capability

The application facilitates device-to-device connections within an approximate range of 10 to 100 meters via Bluetooth, with Wi-Fi Aware extending the range for faster data transfers. Messages are automatically relayed through nearby nodes, allowing a short chain of devices to cover significant distances. Registration requires no phone number, email, or central account; user identity remains localized on the device. Enhanced privacy is maintained through rotating Bluetooth addresses to reduce trackability. Users can establish public chat rooms for open discussion or create password-protected channels for private groups, with all communication persisting despite the absence of cellular service.

Security Architecture and Data Integrity

Security is foundational, not optional. Every conversation is protected with end-to-end encryption using the Noise Protocol XX handshake with ChaCha20-Poly1305. Forward secrecy ensures past communications remain secure even if long-term keys are later compromised. Channel passwords are fortified using the Argon2id key derivation function. All local application data is stored in an encrypted SQLCipher database utilizing AES-256, with hardware-backed key storage via the Android Keystore system (StrongBox when available). A panic mode feature enables immediate deletion of all app data with a single action, employing a three-pass secure erase protocol. Multi-layered stealth modes further reduce Bluetooth visibility for discreet operation.

Feature Set and User Experience

Beyond its core resilience, Noghteha functions as a fully-featured modern chat application. It supports text messaging with user mentions, voice note recording with live waveform visualization, and sharing of images or files up to 100 MB. Threaded replies and link previews are integrated. Location-based channels help users connect with proximate individuals, while familiar IRC-style slash commands (e.g., /join, /who, /msg) facilitate advanced navigation and management. The interface offers comprehensive support for right-to-left languages using the Vazirmatn font, alongside system-wide light/dark themes and Material You dynamic color theming on Android 12 and above.
