Secure • Encrypted • Production-Ready Password Manager

• 🔐 Secure Encryption: AES-GCM encryption with Scrypt key derivation
• ✅ Input Validation: Comprehensive validation for all user inputs
• 🔑 Password Confirmation: Mandatory password confirmation for create/update operations
• 🎨 Enhanced CLI: Beautiful, colorized terminal interface
• 🛡️ Production-Ready: Robust error handling and transaction management
• 🔒 Master Password: Argon2 hashed master password protection
• 📊 Formatted Output: Clean, readable table displays
• 🎲 Password Generator: Cryptographically secure password generation

1. Install dependencies:

   pip install -r requirements.txt

2. Set up environment variables: Create a .env file in the project root:

   DATABASE_URL=your_postgresql_connection_string

3. Set up database schema:

   CREATE TABLE master_key (
       id INT PRIMARY KEY,
       password_hash TEXT NOT NULL,
       salt BYTEA NOT NULL
   );
   
   CREATE TABLE vault (
       id UUID PRIMARY KEY,
       service TEXT NOT NULL,
       username TEXT NOT NULL,
       secret BYTEA NOT NULL,
       created_at TIMESTAMP DEFAULT now(),
       updated_at TIMESTAMP DEFAULT now()
   );

Run the application:

python main.py

1. View passkeys - List all stored passkeys with formatted table display
2. Create passkey - Add a new passkey (requires password confirmation)
3. Update passkey - Update an existing passkey (requires password confirmation)
4. Delete passkey - Remove a passkey (requires confirmation)
5. Generate password - Generate a secure random password
6. Exit - Exit the application
