The vault where your key doesn't exist until you need it.
Core Technologies & Protocols
"SecretMemoryLocker does not store secrets. It remembers how to remember."
- No master passwords
- No stored keys
- No server-side secrets
Access is reconstructed dynamically using:
- your memory
- cryptography
- computational work
Your secrets, your rules — no data ever leaves your device.
Your memory can recover what was never stored.
Regenerate Apple credentials (iPhone passcode, Apple ID, FileVault) deterministically from a single memory-derived key — no backups, no storage, no cloud.
A stolen seed is not always a usable seed.
Protect your paper backups from prying eyes. FakeSeed is an experimental Zero-Knowledge Paper Backup approach that lets you store a "scrambled" version of your seed phrase — without ever entering your private words into a computer.
-
How it works: Generates a deterministic "shuffling map" from your SML secret or key. You manually reorder your seed words on paper using this map.
-
Security model: This is not encryption, but an obfuscation layer. If someone finds your paper backup, they will see a valid set of words — but in the wrong order.
-
Privacy-first: Your BIP39 words never touch the digital world.
-
Important: Designed for 24-word seeds only and should be used as an additional layer, not a standalone protection.
A new version of SecretMemoryLocker is now available.
- Secure handling of the memory-derived key in MemoryEcho
- New PassEcho Mode — standalone key generation container
- Encrypted & obfuscated decoy layers
- Selectable key reconstruction modes (V4 / V5)
- Experimental: FakeSeed (Blind Shuffle Mapping) — deceptive seed obfuscation layer for enhanced security

What's New in v4.03 — Phantom-Step Cascade Key Derivation
SecretMemoryLocker v4.03 introduces an enhanced key derivation model based on a chained Argon2 cascade.
Core idea:
- Initial seed:
k = file_hash_seed - Each secret answer is processed sequentially
- Every step re-derives the key using the previous result as salt
- Final output becomes the deterministic
final_key
Conceptually:
k = file_hash_seed
for answer in answers:
k = Argon2(answer, salt=k)
final_key = k- Multi-layer entropy amplification
- Order-dependent cryptographic strengthening
- No stored master key
- Deterministic and reproducible recovery
This update strengthens resistance against brute-force and structural attacks while preserving full recoverability.
We’ve included a pre-configured challenge to demonstrate our Tri-State Security Logic. Can you distinguish the truth from the mirage?
How to test:
- Download the release and locate the
/Vaultfolder. - Launch the app and click the "Decrypt" button.
- Select
quest_protocol.jsonand then selectSecretML_Vault.zip. - Navigate the three-step cognitive filter:
- Truth Path: Enter 100% accurate data to access the authentic
license.txt. - Decoy Path: Enter "plausible" decoy answers to trigger a Plausible Deniability event. You'll unlock a Honey-pot file, designed to mislead intruders.
- MirageLoop: Any other input leads to an infinite processing loop — wasting an attacker's time without giving away a single bit of error data.
- Truth Path: Enter 100% accurate data to access the authentic

Your Mind is the Password | How to Encrypt Files Without Storing a Key (SML Demo)
SecretML can now derive and securely store a session master key based on your answers — without ever saving the answers themselves.
- One non-reversible 256-bit Master-Hash
- Stored securely in the system keyring
- Enables instant access to multiple archives without re-entering answers
Every encrypted file receives its own unique password, even within the same session.
- Archive key =
SHA256(MasterHash + FileHash) - File hash is stored in archive metadata (comment)
- No two archives ever share the same encryption key
Access to the Master-Key is protected by a recursive question–answer chain.
- Each answer decrypts the next step
- No visible structure or plaintext questions
- Partial knowledge is useless
You don’t enter a password —
you unlock your own memory.
- Answers are never stored
- Only derived hashes exist
- Keyring data can be wiped instantly via UI
Removing archive metadata immediately breaks access —
even if the Master-Key still exists.
A true cryptographic kill-switch.
- Stable Windows build
- No KDF (test version)
- Ready for real-world usage & testing

SecretMemoryLocker v2.12
🛠 Changelog – v2.12 (2025-07-28) Fixes & Improvements:
🧩 Fixed UTF-8 filename issue when extracting files with non-Latin characters (e.g., Cyrillic).
📐 Fixed window sizing bug for smaller screen resolutions and DPI settings.
🦾 🔒 Version 2.11 introduces a new encryption method SHA256 Secure Mode-SML, a patented encryption system that does not require memorizing a password phrase.
- The encryption process uses both the hash of the file (
file_hash) and your answers. - Security is independent of the question length — without the core (
file_hash), brute-force is impossible. file_hashis stored in the ZIP archive comment as a separate key in the format SHA256:.- Think of the JSON file as the key and the archive comment as the lock's core — without the core, the lock cannot be opened.
- All data is securely locked: having the JSON and archive without the core is useless.
- You can split the key and the core between different people for extra security.
- Plausible deniability: just remove the archive comment, and the core is irreversibly lost.
- The key and archive can be stored together without risk, as long as the
file_hashis missing.
The final key for the archive is generated as:
final_key = SHA256(SHA256(answer1 + file_hash) + SHA256(answer2 + file_hash) + SHA256(answer3 + file_hash) + ...).
The SHA256 Secure Mode method combines AES-256-CBC and SHA-256, providing multi-layer protection. The final key is derived from the file hash (file_hash) and the user's answers, making brute-forcing the key virtually impossible without both components.
Thanks to its unique structure (combining answer1 + file_hash and an additional "payload"), this method resembles split-knowledge schemes but has no direct analogs among common solutions.
With properly chosen answers (strong passwords), the method offers a high level of cryptographic security and additional features, such as plausible deniability by removing the archive's comment.

SecretMemoryLocker is a unique offline tool that transforms your personal memories into an unbreakable encryption key. It's designed to securely archive sensitive data and ensure recovery in critical situations.
This guarantees that you — or trusted people like heirs — can access crucial information even if all other passwords are lost.
- Creating a "Digital Will": Store instructions or recovery hints for loved ones in case of unexpected events.
- Protecting Seed Phrases: Securely store clues to a modified seed phrase (based on the FakeSeed concept) instead of saving the phrase itself in plain form.
- Password Archiving: Keep important but rarely used passwords safely encrypted.
- Protecting Any Files: Encrypt personal documents, images, or any digital data for long-term offline storage.
- Create your questions — Choose personal questions only you or your trusted ones would know (e.g. "Where did we first meet?", "What was the name of my first pet?").
- Enter your answers — Provide the exact answers to those questions.
- Attach your files — Upload any files you want to encrypt.
- Get your archive — The app generates a unique key from your answers, encrypts everything using AES-256, and produces a protected
.ziparchive.
To decrypt, simply run the program again and enter the exact same answers.
- ✅ Strong Encryption: Uses the battle-tested AES-256 algorithm to protect your data.
- ✅ Memory-Based Key: The encryption key is generated from a combination of your answers — impossible to guess or brute-force without exact input.
- ✅ Fully Offline: No internet connection is required. Everything runs locally on your computer.
- ✅ No Cloud, No Servers: Your data stays 100% with you. Nothing is uploaded anywhere.
- ✅ Simple Interface: User-friendly window built with Python/Tkinter.
- ✅ Two-Layer Data Separation: The app creates two separate files — an encrypted
.ziparchive and a.jsonfile with encrypted questions. You can store them in different places (e.g., give the.jsonto a trusted person and keep the.zipwith the app in a bank vault). Without both files and the correct answers, access is impossible. - 🎯 Most important: No keys are ever saved. The key is computed in real-time only when the correct answers are provided.
❗ Note: Windows Defender may show a warning about an "unknown publisher" — this is expected for unsigned apps. The file is safe.
