VOID vs KrypterApp

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.

Your private conversations deserve better than "end-to-end encrypted (trust us)." Krypter puts real encryption in your hands: no middlemen, no servers, no fine print. ENCRYPT ANYTHING Photos, documents, voice memos, videos: encrypt any file with HPKE (RFC 9180) and send it any way you like. Only the person you choose can open it. Not us. Not Apple. Not anyone else. ENCRYPTED MESSAGES Write a message, encrypt it, and paste it into iMessage, WhatsApp, email, Signal, whatever. It stays unreadable wherever it travels, except to your recipient. KEYS THAT NEVER LEAVE YOUR IPHONE Every Krypter key is created inside your iPhone's Secure Enclave, the same chip behind Face ID and Apple Pay. The private key can't be exported, copied or read, not even by Krypter. POST-QUANTUM KEY SHARING Invite a contact with a link or QR code. Your public key travels back sealed with ML-KEM, the NIST post-quantum standard, so even a future quantum computer recording today's traffic learns nothing. Everyone sees keys only as SHA-256 fingerprints you can compare in person. CIPHERTEXT THAT SAYS NOTHING Every encrypted message and file starts with a header that looks like random bytes and is padded inside the encryption. Nobody can tell which algorithm was used, whether a password was added, or how big the original really is. PROVE WHO SENT IT Authenticated HPKE lets your recipient verify a message really came from you, not someone pretending to be you. No certificates. No authorities. Pure cryptography. ADD A PASSWORD Stack a shared password on top of the encryption, stretched with 5 million PBKDF2 rounds. Even with the right key, nobody reads it without the password. NOTHING STORED IN THE CLEAR Contacts, key names, dates, settings and the PIN are all sealed on your device with ML-KEM-1024 under the Secure Enclave, and behind your app PIN when it's on. A copy of the phone's storage reveals nothing. TRULY PRIVATE • No account required, ever. Not only not required: there is no way to create one • No network connections: Krypter works fully offline • No data leaves your device unless you share it • No analytics, no tracking, no telemetry • App PIN with a panic PIN, tied to the Secure Enclave and Face ID • Decrypted text hidden from screenshots and screen recordings • Copied text expires from the clipboard after 30 seconds and never syncs to other devices • Privacy screen when you switch apps • No ads, no paywalls BACK UP YOUR CONTACTS Export your contacts in a password-encrypted backup (PBKDF2, 120 million iterations) and restore them anytime. Your keys stay in the Secure Enclave, as they should. STANDARDS-BASED Built on RFC 9180 HPKE, NIST P-256, AES-256-GCM, ML-KEM-768 and ML-KEM-1024, all from Apple's CryptoKit. No proprietary algorithms. No homemade crypto. Krypter is encryption the way it should be: yours.
