SecretML v4.05

What's New in v4.05 — TIMELOCK v1 (PSQC Chronos Protocol)

⏳ TIMELOCK v1 (Chronos Protocol) — Nonce-Based Cryptographic Time Delay

🔐 SecretMemoryLocker v4.05 introduces TIMELOCK v1, an experimental time-delay mechanism for PSQC (Phantom-Step Cascade Container).

This feature turns a randomly generated nonce into a computational time source, creating a cryptographic time capsule effect.

Instead of storing the real nonce, the PSQC container stores only its hash:

PSQC:{
  "nonce_hint": "LEdWTvvka9******",
  "nonce_hash_V1": "48d49beb8cbb82c65d1009fbcbc22c70c1a3dad87a7558b932dfb97ec4f3b928",
  "ciphertext": "Argon2id(secret = nonce, salt = file_hash → Layer0 : base64_payload_data..."
}

To unlock the container, the system must discover the nonce such that:
SHA256(nonce) == nonce_hash_V1

Once the correct nonce is found, it becomes the secret input for key derivation:

Phantom-Step Cascade (nonce-seeded)

nonce
↓

KDF₀ = Argon2(nonce, salt₀)
↓
Decrypt Layer₀ → data₀
↓

KDF₁ = Argon2(data₀, salt₁)
↓
Decrypt Layer₁ → data₁
↓

↓
...
↓

↓
Final Payload (final key + real data)

The derived key decrypts the container using ChaCha20-Poly1305.

---

⚙️ Core Properties

• Computational Time Delay — nonce search space defines unlock time
• Memory-Hard Verification — Argon2id significantly increases brute-force cost
• Server-Optional Architecture — server may store only the nonce (not encrypted data)
• Offline Recovery Possible — nonce can be discovered through computation
• Integrated with PSQC — works alongside Phantom-Step Cascade encryption layers

---

🧩 Unlock Modes

Server-assisted unlock

A server may optionally store the real nonce and release it after a predefined time condition.

Offline unlock

The container can also be unlocked by discovering the nonce through brute-force search.

---

🧪 Potential Use Cases

• cryptographic time capsules
• delayed secret release
• long-term encrypted archives
• experimental time-lock encryption systems

SecretML v4.03

SecretMemoryLocker v4.03

What's New in v4.03 — Phantom-Step Cascade Key Derivation

🔑 Phantom-Step Cascade — Deterministic Final Key Generation

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

🛡 What This Achieves

• 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.

SecretML v4.02

🚀 SecretMemoryLocker v4.02 — The Cognitive Challenge Update

🧠 The Interactive Defense: "Mind-over-Machine"

Version 4.02 introduces a paradigm shift in user authentication. Instead of static passwords, SecretML now utilizes Cognitive Entropy through an interactive challenge-response protocol.

---

🎭 New Feature: The Vault Quest

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:

1. Download the release and locate the /Vault folder.
2. Launch the app and click the "Decrypt" button.
3. Select quest_protocol.json and then select SecretML_Vault.zip.
4. 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.

💡 SecretMemoryLocker — Where memory becomes a labyrinth and security is absolute.

SecretML v3.15

🚀 What's New in v3.15 — Memory-Sync & Chained Recovery

🧠 Memory-Sync (Derived Access Key)

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

---

🔐 Per-Archive Unique Encryption

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

---

⛓ Chained Recovery (Memory Path Protection)

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.

---

🛡 Zero-Knowledge Security Model

• Answers are never stored
• Only derived hashes exist
• Keyring data can be wiped instantly via UI

---

🧨 Instant Access Revocation

Removing archive metadata immediately breaks access —
even if the Master-Key still exists.

A true cryptographic kill-switch.

---

🧪 Status

• Stable Windows build
• No KDF (test version)
• Ready for real-world usage & testing

SecretML v3.09

🚀 What's New in v3.09 — Memory Echo Password Generator (PRO)

🧠 Memory Echo Password Generator (PRO)

Generate infinite passwords dynamically — without ever storing them.

How it works:

• Combines your secret answers + the encrypted file hash (as salt).
• Produces unique, instantly reproducible passwords for any resource.

Steps to use:

1. Activate PRO mode.
2. Select your *_SMLkey.json key-file.
3. Answer your secret questions.
4. Enter the resource name (e.g. GMAIL.COM, FACEBOOK.COM).
5. Get your password instantly.

---

🔐 Password Formats

• SHA-256 (64 chars) — maximum entropy, hexadecimal string.
• SML-Echo (32 chars) — mix of uppercase, lowercase, numbers.

---

📌 Key Rules for Resource Names

• Exact input matters — same name = same password, even small changes break consistency.
• Case insensitive — facebook.com = FACEBOOK.COM.
• Keep it simple — e.g. use just GMAIL.COM.

---

🛡 Why Memory Echo?

• On-the-fly — passwords never stored, exist only during generation.
• Offline mode — once activated, no internet is needed.
• Total control — only you, with answers + key-file, can restore passwords.

💡 Pro Tip: Use Memory Echo to create your master password (e.g. for Google Account).
This ensures guaranteed recovery and unbreakable security for your entire digital life.
