LottisCrypt: The Ultimate Cross-Platform Vault
Take absolute control of your digital privacy. LottisCrypt is a powerful, offline encryption engine that lets you lock down your sensitive files and share them securely with anyone.
Built on state-of-the-art cryptography (AES-256-GCM and Elliptic Curve Cryptography), LottisCrypt ensures that only the people you explicitly authorize can open and view your files. There are no cloud servers to get hacked, no accounts to create, and no passwords to remember.
KEY FEATURES:
• Cross-Platform Sharing: Encrypt a file on your iPhone and seamlessly decrypt it on any other device that runs LottisCrypt.
• Military-Grade Security: Powered by industry-standard AES-256 and Ed25519 digital signatures. Your data is sealed in an unbreakable mathematical lockbox.
• Zero-Trust Architecture: LottisCrypt operates entirely offline on your device. We don't have your keys, we don't see your files, and we don't have servers to breach.
• Visual Fingerprinting: Verify who you are talking to using our unique, 8-emoji visual safety numbers. No more guessing if a key is authentic.
• Magic Links: Add friends to your secure address book instantly by sharing a simple URL.
• Native File Integration: Save and organize your decrypted .lot files directly in your device's native Files app.
HOW IT WORKS:
Generate your unique Identity Key with one tap.
Share your "Magic Link" with a trusted friend to swap keys.
Select any document, photo, or video, and lock it to their identity.
