With VOID, you can: • Encrypt your texts securely and offline. VOID uses AES-256 encryption to protect your information with military-grade security. All encryption and decryption happen locally on your device - your data never leaves your phone. No cloud storage, no internet connection, no third-party servers. Your information stays completely offline. • Encrypt your files with AES-256 + Argon2id. VOID protects not just text, but your files too. File encryption combines AES-256 with Argon2id - a memory-hard key derivation function that won the Password Hashing Competition - making brute-force attacks practically impossible. Encrypt any file directly on your device with no internet connection required. • Customize encryption parameters. Take full control of how your data is secured. Fine-tune settings including salt length (0-256 bytes), number of iterations (up to 500), memory usage (up to 1024 MiB), parallelism (up to 6 threads), and key length (up to 224 bytes). Apply up to 7 layers of encryption for maximum security. Advanced users can optimize encryption strength according to their needs. • Use a hidden key (VOID Secret). VOID Secret is a hidden key variant generated per device. Each device can generate up to 999 different hidden keys, providing an extra layer of protection. Only you can decrypt messages with the correct VOID Secret - your communication stays fully confidential even if the main password is shared. The hidden key is optional but adds meaningful security for sensitive conversations. • Encode your texts in emoji. Transform your messages into emoji sequences. VOID converts your text to Base64 and then into emojis, so you can send encrypted messages that look like strings of symbols. Adds a layer of secrecy while making encryption visually engaging. • Generate and customize QR codes. Turn any encrypted text into a QR code. Customize appearance - colors, style, and format - then export in multiple formats and share however you choose. Additional Features: Offline-first design: VOID never connects to the internet, stores, or transmits your data. No accounts or registration: No personal information is ever required. Temporary decryption timer: Set a self-expiring timer so messages can only be decrypted within a limited time. Security Mode: Blocks screenshots and screen recordings completely. Multilingual support: Use VOID in your preferred language. Intuitive UI/UX: Designed with Apple's guidelines in mind, with animations, haptic feedback, and simple navigation. With VOID, your information is encrypted and under your full control. You decide how, when, and with whom to share it. Secrets truly stay secret.
