NowiChat is a cutting-edge chat application that utilizes Bluetooth networks and hybrid cryptography for enhanced security. It encrypts MAC addresses and stores all information locally, ensuring user privacy. With a panic button for instant data deletion and a robust tech stack, NowiChat prioritizes security while delivering a seamless chat experience.

NowiChat is an innovative chat application designed for secure communication over Bluetooth networks, employing advanced hybrid cryptography protocols to enhance user privacy and data protection. This application ensures that all communications remain confidential through the use of symmetric cryptography to encrypt MAC addresses, securing user identities and interactions.

Key Features:

Hybrid Cryptography: Utilizing a combination of symmetric and asymmetric encryption, NowiChat enhances security by sharing symmetric keys via asymmetric methods. This approach ensures that all sensitive information is well-guarded.
Local Data Storage: All data is stored locally on the device, minimizing the risk of external breaches and enhancing overall control over personal information.
Panic Button: In the event of a security concern, users can quickly erase all personal data with the built-in panic button, providing peace of mind in critical situations.

Tech Stack:

Cryptographic Tools: Includes AndroidKeyStore, Cipher, AES-256, SHA-256, RSA-2048, and MessageDigest for robust security measures.
Database: The use of SQLite ensures efficient data management within the application.
