CorePass CLI V1.0

CorePass CLI is a secure, offline, and lightweight password manager built for those who want security without the fluff. Store your logins, generate bulletproof passwords, and manage everything with a slick terminal interface—all while keeping your data locked down with military-grade encryption. No internet, no nonsense, just pure hardcore password management.

Features

• Interactive Menu: Navigate with arrow keys and Enter through options like Add Entry, list Entries, Generate Secure Password, Export Vault, Delete Vault, Help, and Exit.
• Add Entry: Store service name, username, and password in your encrypted vault. Press Esc to cancel anytime.
• List Entries: View all entries with a searchable list. Type letters to filter services in real-time, use arrows to select, and dive into actions for each entry.
• Entry Actions: For each entry, you can:
  • Edit Service, Username, or Password.
  • Show Password (visible for 5 seconds before hiding).
  • Copy Password to clipboard (cleared when you press Enter or exit the program).
  • Delete Entry with confirmation.
  • Access a Help menu with action descriptions.
• Generate Secure Password: Create a random 12-character password with a mix of letters, numbers, and symbols. Show it (S), copy to clipboard (C), or return (Enter).
• Export Vault: Copy your encrypted my_vault.vault file to a chosen folder (defaults to Documents).
• Delete Vault: Permanently delete the vault file with confirmation—use with caution!
• Secure Input: Passwords are masked with ******** in the terminal and never appear in command history.
• Clipboard Security: Passwords copied to the clipboard are cleared when you press Enter (after "Password copied to clipboard! Enter to clear clipboard and return...") or when the program exits.

Encryption

CorePass uses AES-256 in CBC (Cipher Block Chaining) mode with PKCS7 Padding, ensuring your data is locked tight. The encryption key is derived from your master password using PBKDF2 (Rfc2898DeriveBytes) with:

• Iterations: 100,000
• Key size: 256 bits
• IV size: 128 bits
• Hash algorithm: SHA-256

Everything is 100% local and offline, so your data never touches the internet. The built in password generator creates military-grade passwords to keep your accounts secure.

Security Warnings

• Do NOT store seed phrases or private keys for cryptocurrencies or credit card details in CorePass. If you choose to do so, it’s at your own risk.
• Vault File Safety: The my_vault.vault file is encrypted, but if you lose it, your data is gone. Keep a secure backup!
• Keyloggers: Be cautious of keyloggers, especially for sensitive data. Consider using a clean virtual machine or TailsOS for maximum security.
• Master Password: Your vault’s security depends on a strong master password. Choose wisely and memorize it there’s no recovery option.
• Physical Backups: Always maintain a secure physical backup of your logins and critical data.
• Clipboard: Passwords are cleared from the clipboard.

Requirements

• UTF-8 Terminal: Ensure your terminal supports UTF-8 for compatibility with special Latin characters (e.g., ñ, ç,).
