About this app

Do you really trust the big IT corporations? Government agencies have in the past forced companies to install backdoors in their encryption. Whistleblowers have documented that digital communications are systematically collected and analyzed. End-to-end encryption only protects you as long as you trust the provider — and that trust is not guaranteed. RotorCrypt X Mobile replaces that trust with mathematical provability. Encryption happens entirely on your device before your message touches any messenger. No provider, no authority, no corporation has access — because it is technically impossible.
HOW IT WORKS
Write your message in RotorCrypt X Mobile. The app encrypts it fully on your device and generates a cryptographic block. Send this block via WhatsApp, Telegram, Signal, SMS, Email, or any other channel — what is sent looks like random data garbage to any observer. Only your recipient, with the correct RotorCrypt app, can restore the plaintext. Not the messenger provider. Not the network operator. Not an authority. Not an attacker intercepting the traffic.
UNBREAKABLE ENCRYPTION
50 rotors with 65,536 Unicode characters generate over 10^240 possible configurations — a brute-force attack would take longer than the age of the universe. Combined with AES-256-GCM, the standard of NATO and military agencies worldwide, this encryption cannot be broken even with future quantum computer technology.
EIGHT INDEPENDENT SECURITY LAYERS
The security architecture is based on Kerckhoffs's principle — secure even if the complete algorithm is publicly known.

Enigma mechanism (50 rotors, modernized)
AES-256-GCM
HMAC-SHA3-256
HKDF-SHA3-256 key derivation
Perfect Forward Secrecy

ZERO TRUST — ZERO COMPROMISES
✓ No servers. No cloud. No registration. No account.
✓ All keys stored exclusively on your device
✓ Works completely offline — no internet connection required
✓ Two parties exchange a keyfile once — after that the app handles everything
✓ Auto-lock on inactivity and in background
✓ Clipboard and display field are automatically cleared
✓ 10 incorrect password entries = all data irreversibly deleted per military standard DoD 5220.22-M
WORKS WITH ALL MESSENGERS
WhatsApp, Telegram, Signal, Threema, Wire, Viber, Discord, SMS, Email and more. RotorCrypt X Mobile is not a replacement for your messenger — it is the security layer above it.
WHO IS THE APP FOR?
For companies that need to protect trade secrets. For lawyers, doctors and journalists bound by confidentiality. For activists and private individuals who do not want to leave their communication to the goodwill of platform operators. And for everyone who has understood: privacy is not a luxury — it is a fundamental right.
PRO VERSION
Unlocks all 50 rotors and advanced features. No subscription. No hidden costs. One-time payment.
Security that does not depend on trust. But on mathematics.
Military-grade encryption for every messenger. Offline. No account needed.
