RotorCrypt X-Files

RotorCrypt X-Files: offline file & folder encryption with triple-layer security, RCX sharing, a built-in Password Vault, 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.

Completely independent from the file Vault, RotorCrypt X-Files also includes a built-in Password Vault: generate strong, customizable passwords with a built-in password generator, adjustable from 4 to 64 characters, and store your website credentials (URL, username, password) in an encrypted table. The Password Vault is protected with the same level of encryption as your files, making it practically impossible for anyone to read out your stored passwords.

Contacts can be personalized with individual avatars, making it quick and easy to recognize who you're sharing files with at a glance.

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. This handshake is itself protected against man-in-the-middle attacks, so an attacker cannot secretly intercept or impersonate either side during first contact. Only that one recipient can ever decrypt the file — not even with significant technical effort. Any tampering with a file or message 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 with man-in-the-middle protection, 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.

Whether you want to lock away sensitive files, share them safely with someone you trust, or finally get your passwords out of that unprotected text file — RotorCrypt X-Files gives you serious, no-compromise protection without any of the usual cloud, account, or subscription hassle. Try it and see how simple real security can be.

Update — October 1, 2026 (v1.2.6.4)

New Features

• Reworked navigation: the back-arrow icon now points up instead of left, and is now positioned under the flags
• New step/jump logic for the sidebar tree: an adjacent click opens or closes immediately, a jump only sets the item active first
• Replaced the plus field with a true "Drag & Drop Export" field, translated into 19 languages, with font size automatically adjusting per language
• The export field is now a pure drop target — the click dialog has been removed
• Dragging a file or a folder onto the export field now opens the export dialog directly
• Added a right-click context menu for folders in the list/detail view
• Added drag & drop for moving folders and files in the list/detail view
• Replaced the "+" field with the same "Drag & Drop Export" field in the list/detail view, matching the tile view
• The updater window now scales up to 350% (window, bar, font, banner image)
• Increased the font size of the inactivity popup from 12 to 14
• Shifted the SFX password fields up by 2 lines
• The speaker icon can now also be toggled by clicking the icon itself
• Added the version number to the window title

Improvements

• Added a DPI-awareness fallback (Windows), so scaling now works correctly on 4K displays at 200%/300%

Bug Fixes

• Fixed the sidebar tree incorrectly jumping to the parent folder when clicking an expanded ancestor folder
• Fixed a double highlight on the golden border between label and card in the export field
• Fixed the export field showing the internal ID instead of the real folder name
• Fixed double folder nesting on export
• Fixed the export field not appearing in subfolders in the list/detail view
• Fixed the export field's border incorrectly staying highlighted after a selection change
• Fixed avatar zoom dialog scaling at high OS zoom levels (e.g. 300%)
• Fixed avatar zoom dragging not working in all 4 directions on the very first open
• Fixed avatar zoom drag scaling to use the actual canvas size instead of a fixed constant
• Corrected a base-file mistake — all changes reapplied to the correct file

Update — September 2, 2026 (v1.2.5.3)

New Features

• Introduced a tree view: subfolders are now collapsed by default and only expand when clicking the arrow, icon, or name.
• Added "Rename" functionality: contact names can now be changed via right-click without affecting encryption.
• Added a Password Vault: a dedicated section for securely storing passwords, including a built-in password generator.
• Added "Change Avatar" functionality: a contact's avatar image and name can now be changed together via right-click.
• Added Italian as the 13th supported language.

Improvements

• Simplified password setup during the initial launch.

Bug Fixes

• Fixed a bug where files with identical names in different folders were incorrectly treated as duplicates and automatically renamed.
• Fixed unreliable keyboard deletion (Delete key) for folders.
• Fixed a display bug where, after deleting all contacts, the last selected contact name remained visible in the dropdown.
• Fixed a bug that prevented users from decrypting their own encrypted messages.
• Fixed scaling-related issues.
• Fixed the in-app update process, which now completes reliably and error-free.
