Password Generator

A GUI-based password generator written in Object Pascal using Lazarus/Free Pascal. This application allows users to generate one or more strong and customizable passwords, with options for character sets, length, and clipboard integration. User preferences are stored automatically for convenience.

Features

• Customizable Password Generation
  • Select inclusion of uppercase, lowercase, numbers, full symbols, or custom symbol sets.
  • Specify password length and the number of passwords to generate.
  • Option to require the first character to be lowercase.
• Clipboard Integration
  • Copy all or selected passwords to the clipboard with a single click.
• User Preferences
  • Settings are saved to and loaded from an INI file (PasswordGen.ini) in the user's home directory.
• Easy-to-use GUI
  • Intuitive controls and real-time generation.

How It Works

• Choose your desired password options using checkboxes and input fields.
• Click "Generate" to produce your passwords.
• Passwords are displayed in a list and automatically copied to your clipboard.
• Click the "Copy to Clipboard" button to copy selected or all passwords.
• User settings are saved automatically on close and reloaded on startup.

Main Components

• TForm1: The main form, containing all controls and logic.
• Character Sets: Uppercase, lowercase, numbers, full symbols, or user-defined custom symbols.
• Settings Storage: Uses TINIFile to persist user preferences.
• Password Logic: Ensures selected character types are present and shuffles for randomness.
