Key Features

• Flexible Character Sets: Customize your password character pool with the following options:

  • a: Lowercase alphabet [a-z]
  • aa: Uppercase alphabet [A-Z]
  • s: Symbols [#$%^*_-=+~;[<{(:&|@:)}>];~.?!]
  • n: Numbers [0-9]
  • Custom characters: Enter your own characters or words to add to the pool for generating unique passwords.

• Customizable Password Length: Specify the desired password length as the first argument for precision in password complexity.

• Default and Custom Modes:

  • Default Mode: If no additional character set arguments are provided, the generator defaults to using lowercase, uppercase, symbols, and numbers.
  • Custom Mode: Specify character sets to tailor your password (e.g., only lowercase and numbers).

Usage

Enter the command with:

1. The desired password length as the first argument.
2. Optional character set arguments (a, aa, s, n) and/or custom strings to define the password's content.

Examples:

# Default mode (uses all predefined character sets) `["a", "aa", "s", "n"]`:
>> 16
Yours generated password[16]: jY*3vP6a@zWr#9X&

# Custom mode (using lowercase, symbols, and numbers only):
>> 12 a s n
Yours generated password[12]: d1$e!r8p9t@w

# Custom mode with custom strings (e.g., "@_@^_^00 "):
>> 10 a @_@^_^00 s 
Yours generated password[10]: :q::{:~x$<

Improvements & Bug Fixes

• Enhanced Input Validation: Prevents crashes from empty or invalid inputs.
• Increased Security: Incorporates randomized shuffling and ensures secure character selection.
• Streamlined Output: Clear, user-friendly output with concise error messages for any invalid inputs.
