Password Manager with GUI in Python

This is a Python-based password manager that allows users to securely store and manage their passwords with encryption. The application features a graphical user interface (GUI) built with tkinter, and it supports adding, searching, generating, and exporting passwords. Passwords are encrypted and saved locally, ensuring data security.

Features

• Encryption: Passwords are encrypted using the cryptography library, ensuring that sensitive data remains secure.
• Password Generation: Generate random, secure passwords based on customizable settings (including uppercase, lowercase, digits, and special characters).
• Add Passwords: Add new passwords for accounts, usernames, and optional notes. Each password is securely stored after encryption.
• Password Search: Search for stored passwords by account or username to quickly retrieve specific entries.
• Export/Import Passwords: Export passwords to a CSV file for backup and import passwords from CSV to restore them.
• Password Strength Highlighting: Weak passwords (less than 8 characters) are highlighted in red in the interface.
• Copy Password to Clipboard: Double-click a password to copy it securely to the clipboard.

Libraries Used

• tkinter: For creating the graphical user interface.
• cryptography: For encrypting and decrypting passwords.
• csv: For reading and writing passwords to a CSV file.
• random & string: For generating secure passwords.

Usage

• Add a New Password:

  • Fill in the account name, username, password, and optional notes.
  • Click the "Add Password" button to save the entry.

• Generate a Secure Password:

  • Click the "Generate New Password" button to create a password with customizable options (such as including uppercase letters, digits, and special characters).
  • The generated password will be automatically inserted into the password field.

• Search for a Password:

  • Use the search bar to filter stored passwords by account or username.
  • Click the "Search" button to view the filtered list.

• Export and Import Passwords:

  • Click the "Export Passwords" button to save all stored passwords to a passwords.csv file.
  • Use the "Import Passwords" button to load passwords from a CSV file into the application.

• Copy Password to Clipboard:

  • Double-click any password entry in the password list to copy the decrypted password to your clipboard.
  • A success message will be shown confirming that the password has been copied.

Security Notes

• Encryption:

  • Passwords are encrypted using the cryptography library and a randomly generated key stored in a file called secret.key.
  • This encryption ensures that even if someone gains access to the password storage file (passwords.csv), they won't be able to read your passwords without the encryption key.

• Password Storage:

  • Passwords are stored in the passwords.csv file in an encrypted format.
  • The secret.key file is necessary for decrypting the passwords.

• First-Time Setup:

  • When you run the application for the first time, a new encryption key will be generated, and a file named secret.key will be created in the application directory.
  • Important: Make sure to back up the secret.key file. If it is lost, you won't be able to decrypt your passwords.

• Backup:

  • Regularly back up both the passwords.csv and secret.key files to ensure you don't lose access to your data.
