secure-password-manager 1.6.0

A secure local password manager

🔐 Password Manager

A secure Password Manager built with Python that securely stores your passwords locally using strong encryption.

🚀 Features

• Secure Storage: All passwords encrypted with Fernet symmetric encryption
• Password Management: Add, view, edit, and delete passwords
• Security Analysis: Password strength evaluation and suggestions
• Password Generator: Create strong, random passwords
• Master Password: Protect access with a master password
• Two-Factor Authentication: Additional security with TOTP (Time-based One-Time Password)
• Categorization: Organize passwords by category
• Security Audit: Find weak, reused, expired, or breached passwords
• Backup & Restore: Export/import functionality
• Password Expiration: Set expiry dates for passwords
• Command-Line Interface: User-friendly CLI with color formatting
• GUI Interface: Optional PyQt5 graphical interface
• Activity Logging: Track all important actions

🔒 How It Works

Security Model

This Password Manager uses a multi-layered security approach:

1. Master Password: Access to the application is protected by a master password that is never stored directly. Instead, a salted hash is stored using PBKDF2 with 100,000 iterations.

2. Encryption: All passwords are encrypted using Fernet symmetric encryption (AES-128 in CBC mode with PKCS7 padding).

3. Key Management: The encryption key is stored locally and is used for encrypting/decrypting the stored passwords.

4. Database: Passwords are stored in a local SQLite database, with the password values stored as encrypted binary data.

5. Backup Protection: When exporting passwords, the entire backup file is encrypted using the same strong encryption.

Data Flow

1. When adding a password:

   • Password is encrypted using the local key
   • Encrypted data is stored in the SQLite database

2. When viewing passwords:

   • Encrypted data is retrieved from the database
   • Each password is decrypted for display

3. When exporting passwords:

   • All passwords are decrypted
   • The entire password list is serialized to JSON
   • The JSON is encrypted and written to a file
