RotorCrypt X
Free offline encryption – Enigma + AES-256-GCM – no cloud
...Six cryptographic layers: Enigma rotor cipher with up to 50 rotors and 241-digit key combinations. AES-256-GCM military-grade authenticated encryption. HKDF-SHA3-256 key derivation with Perfect Forward Secrecy. Argon2id password hardening — 256 MB RAM per attempt, brute-force practically impossible even on GPU clusters. Split Key via ECDH Curve25519 — neither party alone can compute the shared key. Forward Secrecy²: contact ID permanently deleted after handshake.
No cloud. No server. No internet required. Quantum-resistant with 2^768 key space. Anti-debug detection, replay protection, key destruction on tampering. ...
