A simple, cryptographically secure password generator written in Go.

• Specify any password length (minimum 4 characters)
• Every generated password contains at least one character from each category:
  • Lowercase letters: a-z
  • Uppercase letters: A-Z
  • Digits: 0-9
  • Special characters: @ . -
• Uses crypto/rand for cryptographically secure randomness
• Fisher-Yates shuffle prevents predictable character positions

Prerequisites: Go 1.18+
