RotorCrypt X-Files

RotorCrypt X-Files: offline file & folder encryption with triple-layer security, RCX sharing, and self-extracting EXE.

Description

RotorCrypt X-Files is a Windows encryption program built to protect files and folders. It works fully offline: no cloud, no external server, and no account required — all encryption happens locally on your device.

At its core is the Vault, a digital safe where files and folders are automatically encrypted in three independent layers, a level of protection that cannot realistically be broken with current or foreseeable computing power. An optional fourth layer can be enabled for maximum security, at the cost of larger file size and slower processing. Inside the Vault, files behave like a normal folder: double-click to open and edit, and the file is re-encrypted automatically once closed. Whole folders can be moved in and out just as easily as single files. Files inside the Vault are stored under randomized, identical-looking .rcx names, so their original names and content stay hidden even if someone opens the Vault folder directly on the file system. A one-click privacy screen hides the entire Vault instantly, and an adjustable auto-lock (1–5 minutes) locks the program and clears all fields after inactivity. Deletion uses a military-grade multi-pass wipe method instead of a simple file reference removal.

RotorCrypt X-Files can encrypt individual files as RCX files for secure delivery to one specific, confirmed contact. Creating an RCX file requires both sides to have completed a handshake beforehand, after which sender and recipient are mutually verified as trusted contacts — no password is needed to decrypt, since trust has already been established through the handshake. Only that one recipient can ever decrypt the file — not even with significant technical effort. Any tampering is detected immediately and decryption is refused. RCX files can be sent through any messenger or program without special transfer requirements. Unlike encrypted text messages, which for security reasons can only be decrypted once, an RCX file can be decrypted multiple times as long as the contact still exists; deleting the contact makes the file permanently inaccessible.

RotorCrypt X-Files can also package encrypted content as a self-extracting EXE file, requiring no separate decryption software on the recipient's side. An optional expiration date causes the file to delete itself automatically if opened after the deadline, and it self-deletes after five failed password attempts. Passwords are hardened with Argon2id.

RotorCrypt X-Files builds on the same cryptographic foundation as RotorCrypt X's message encryption, but goes further: up to 100 rotors (versus 50) at 65,535 characters, combined with AES-256-GCM and modern key derivation. No proprietary or self-invented cryptography is used anywhere — only algorithms that are scientifically vetted, peer-reviewed, and used worldwide: Argon2id, AES-256, ChaCha20, SHA3-256, and classic rotor encryption based on the historical Enigma machine. Per-contact key exchange uses ECDH over X25519, tamper detection uses AES-GCM combined with HMAC-SHA256, and secure deletion follows the DoD 5220.22-M standard. Key exchange itself uses two independent 256-bit random numbers that are combined and then permanently discarded, leaving no way to reconstruct the shared key afterward.

The program itself is password-protected, with the password hardened using Argon2id (256 MB memory, 3 iterations, 4 parallel threads) and never stored in plaintext.
