✨ New Features

• Added automatic clipboard cleanup 15 seconds after copying a password.

🔒 Security Improvements

  • Prevents password leakage via memory dumps or debugging tools.
• Guaranteed cleanup on exit:
  • All passwords, encryption keys, and temporary data are securely erased.

🧹 Improvements

(Previous release: Usage Stats, Auto-clean/lock, Secure Folder)

CryptoZ v2.2.0

Update to CryptoZ v2.2.0
📦 CryptoZ v2.2.0 — "Secure Folder & Live Encryption"
I'm excited to announce the biggest update yet — CryptoZ is no longer just a file encryption tool. It’s now a proactive security system with real-time protection, intelligent automation, and a seamless user experience.
🚀 What’s New?
🔐 Secure Folder — Protected Folder with Live Access
Select any folder — and it becomes automatically encrypted
All new files are instantly encrypted with .encrypted extension
Files are decrypted into a secure temp folder when opened
Edit, save — and they’re automatically re-encrypted
✅ Like VeraCrypt, but simpler, smarter, and built-in.

🔄 Edit & Save Back
Open a file → decrypted to .temp_decrypted
Edit in any app (Word, Notepad, etc.) → save
CryptoZ detects changes → re-encrypts the file
Supports: .txt, .docx, .pdf, .xlsx, and more

🧹 Auto-Clean & Auto-Lock
🔒 Auto-Lock on Exit: stops monitoring & cleans temp files on app close
🧽 Auto-Cleanup: removes .temp_decrypted, .enc.tmp, .tmp, *~ on startup/shutdown
🛡️ No traces left behind — perfect for shared or public computers

📊 Usage Statistics
Real-time counters:
🔢 Files encrypted
📤 Files decrypted
🕐 Active sessions
⏳ Last session timestamp
Displayed in About → 📊 Stats — updates live
Data stored in cryptoz_config.json — persistent & safe

🧩 Improvements & Fixes
✅ Dynamic config recovery: restores defaults if config is corrupted
✅ Unified .encrypted extension — now consistent across all modules
✅ Fixed issues with DEFAULT_SETTINGS, backup_config
✅ Real-time UI updates via callback system
✅ Enhanced About tab with organized sub-tabs

💡 Why It Matters?
🏢 For Business: secure shared folders, protect confidential documents
🛡️ For Privacy: zero exposure of decrypted files
🚀 For Simplicity: encryption works silently — you focus on work

🙌 Thank You!
CryptoZ is an open-source project built for education, ethics, and professional use.
