Describe the Add-ons or Changes You've Made

Give a clear description of what you have added or modified.
This is a simple password manager built with Streamlit, allowing users to securely store, encrypt, and manage their passwords. The application uses AES encryption (via the cryptography library) to securely store passwords (in a passwords.txt file), and it includes functionality to generate encryption keys and check password strength before storing passwords. Users can add passwords, view stored passwords, and generate encryption keys all through an easy-to-use graphical interface.

Key Features

• Encrypts and stores passwords securely.

• Ensures the password is strong before storing it.

• Decrypts and displays saved passwords when requested.

• Generates and stores a unique encryption key for secure password storage.

• Runs in a browser, supported across multiple platforms.

• I have described my changes.
