🔐 Lock — Multi-level Text Encoder / Decoder

Lock.exe — standalone Windows app (≈ 7 MB) Developer: Sohamdip Santra

A compact, terminal-based encryption tool that encodes and decodes text using multiple random base transformations (bases 2–16). Packaged as a single Windows executable so testers can run it without installing Python.

---

🚀 Features

• Multi-level random-base encoding (2 → 16).

• Saves encoded output as JSON in the exact format:

  {"message": "<encoded string>", "key": [2,3,5,...]}
  

  (One-line JSON — ready to copy/share.)

• Decode using saved JSON files (auto-detect latest file, scan subfolders).

• Colorful CLI prompts for easy use (requires terminal supporting ANSI colors).

• Small single-file app — ~7 MB.

🗂 IMPORTANT — Where to put Lock.exe

Please place Lock.exe inside its own folder before running it (for example: C:\Users\YourName\LockTool\). Why: Lock saves encoded .json files in the same folder (or subfolders) where the program is located. If you run the .exe from different locations, encoded files may be scattered across your system and become hard to find. Keeping the app in a dedicated folder keeps everything neat and traceable.

Recommended layout:

C:\Users\You\Lock\Lock.exe
C:\Users\You\Lock\EncodedFiles\encoded_2025...
C:\Users\You\Lock\log.txt

🧭 How to Use (quick)

1. Put Lock.exe in a new folder (recommended).

2. Double-click Lock.exe or open a command prompt in that folder and run:

   ./Lock.exe

3. Choose:

   • 1 — Encode message
   • 2 — Decode message
   • 3 — Exit

4. Follow on-screen colored prompts:

   • When encoding you’ll be asked for the message and number of encoding levels.
   • You can press Enter to accept a timestamped default filename.
   • You can choose to save encoded files in a subfolder.
   • When decoding the tool scans the program folder and subfolders, lists JSON files with indexes, and lets you pick by number or press Enter to decode the latest.

✅ Example encoded output (one-line JSON)

After encoding, Lock prints the exact saved JSON in one line:

{"message":"132 213 021 ...","key":[4,2,9]}

You can copy that line or open the saved .json file later.

⚠️ Windows SmartScreen / Security

When opening the .exe for the first time, Windows may show:

“Windows protected your PC” or “Unknown publisher”

This is normal for unsigned personal apps. To run:

• Click More info → Run anyway.

If you want to avoid such warnings later, consider code-signing the executable (optional / advanced).
