What is Nahoft?
Nahoft is an offline mobile application designed for Android and iOS devices that enables users to encrypt text messages into either images or meaningful Persian word strings. The app does not function as a messaging service itself but rather as a tool for securing communications, allowing encrypted content to be sent through any existing messaging platform. It operates completely offline without relying on servers for encryption, decryption, or message transmission, ensuring user privacy and data security.
The application offers multiple security features including password protection, self-destruct codes for data erasure, and the ability to store or delete received messages after decryption. Nahoft has undergone two security audits by Cure53 researchers, with their recommendations implemented to enhance app security. It is free, open-source, and ad-free, with development supported by the non-profit organization United for Iran.
