This tool allows users to configure password characteristics such as inclusion of uppercase, lowercase, numbers, symbols, and more, while also preventing duplicate or sequential characters.

Features

• Customizable Character Sets: Supports uppercase, lowercase, digits, and symbols, with options for custom sets.
• Security Options: Prevents duplicate and sequential characters for added password strength.
• Flexible Length and Format: Easily configurable to generate passwords of any length, with options for starting with letters or numbers.
• Cryptographic Randomness: Uses RandomNumberGenerator to ensure secure and unpredictable password generation.

Usage

Console Application

You can use the Password Generator from the command line by passing arguments to control the length and features of the generated password.

Example Command:

Available Options:

• --no-uppercase : Exclude uppercase letters from the password.
• --no-lowercase : Exclude lowercase letters from the password.
• --no-numbers : Exclude numbers from the password.
• --symbols : Include symbols in the password.
