Why the name “Poottu”?

Poottu (பூட்டு, pronounced Poo-ttu) means “lock” in Tamil, symbolizing security and protection. The name reflects the app’s purpose: a simple, safe, and trusted password manager.

Getting Started

Prerequisites

• Python 3.12+
• A virtual environment is recommended.

Installation

1. Clone the repository and enter the project directory.

2. Create and activate a virtual environment:

• Windows:
  • python -m venv venv
  • venv\Scripts\activate
• macOS/Linux:
  • python3 -m venv venv
  • source venv/bin/activate

3. Install dependencies:

• pip install -r requirements.txt
  • or
• pip install "PySide6>=6.5.0" "argon2-cffi>=21.3.0" "pynacl>=1.5.0" "cryptography>=41.0.0" "platformdirs>=3.0.0" "zxcvbn>=4.5.0"

Running

• From the project root:
  • python src/poottu/main.py

On first run without a vault, the Create window appears to set a master password. If a vault already exists, the Unlock window will prompt for the master password.

Usage

Create Master Password

• Enter and confirm a strong password.
• Requirements:
  • At least 12 characters.
  • Contains lowercase, uppercase, number, and special character.
• The strength checker will guide improvements if needed.
• Press Create to initialize the vault.

Unlock Vault

• Enter master password and press Unlock or hit Enter.
• Use Show to verify the password if necessary.
• On error, an “Invalid master password” message appears.

Main Window Overview

• Groups (left): pick a group to filter entries.
• Search (top): filters entries across Title, Username, URL, and Notes as text is typed.
• Entries (top-right): table with Title, Username, masked Password/Old Password, URL, Notes preview, and Expires.
• Preview (bottom-right): see details for the selected entry and reveal/hide password.

File Menu

• Add Entry: create new credential records.
• Edit Groups: add, rename, and delete groups.
• Backup: export an encrypted backup file.
• Restore: import a previously exported encrypted backup.
• Clipboard → Configure Clear Timer…: choose the seconds before the clipboard is auto-cleared (0 disables).
• About: version, author, project URL, and full MIT license.
• Exit: close the app.

Entries

• Add Entry: choose Group, then fill Title, Username, Password, Old Password, URL, Notes, optional Expires.
• Edit Entry: right-click rows or select a row and press F2.
• Delete Entry: right-click rows or press Delete, then confirm.

Copying Safely

• Right-click an entry row to copy Username/Password/URL/Old Password/Notes.
• If the clipboard clear timer is enabled, copied data is automatically cleared after N seconds.
• A small HUD toast displays “Copied. Will clear in Ns” or “Copied.” when timer is disabled.

Keyboard Shortcuts

• Ctrl+N: Add Entry
• Ctrl+G: Edit Groups
• Ctrl+B: Backup
• Ctrl+R: Restore
• F2: Edit selected entry
• Delete: Delete selected entry

Backup and Restore

• Backup creates an encrypted backup file; keep it in a safe location.
• Restore replaces current contents with the backup’s data after validation.
• Recommended:
  • Maintain multiple backups.
  • Verify backups periodically by restoring in a separate environment.

Security Notes

• Offline-first: no automatic syncing or telemetry; everything stays local unless a manual backup is performed.
• Modern, authenticated encryption protects sensitive fields.
• Strong key derivation and header checks ensure data integrity and tamper resistance.
• Clipboard timer reduces the time secrets remain accessible to other apps.

Best Practices

• Use unique, strong passwords for each account.
• Rotate passwords periodically; use the Expires field to track changes.
• Keep multiple encrypted backups in different secure locations.
• Never share the master password; it cannot be recovered if lost.
• Lock the OS session or close the app when stepping away from the computer.
• Keep the OS and Python environment up to date for security patches.

Troubleshooting

• Invalid master password:
  • Check keyboard layout, caps lock, and try again.
• Clipboard not clearing:
  • Ensure the timer isn’t set to 0 (disabled) in File → Clipboard → Configure Clear Timer….
• Text readability:
  • The app uses accessible styles for light/dark themes. If a custom OS theme overrides defaults, consider adjusting system appearance for contrast.
