## What is Security Guard?

[Security Guard] Local-Priority Encryption and Security Tools
This is a local toolkit designed for learning, practice, and daily security handling. Whether it's text encryption/decryption, hash verification, high-strength password generation, or fun password training, it can handle it all. Your data stays on your device for greater security.

【Core Functions】 Crypto Lab: Offers a variety of classic and modern conversion tools: Caesar, Virginia, Atbash, ROT13, Rail Fence, Base64, Hexadecimal, Binary, Morse Code, URL escaping, reversal, keyword mixing, etc. Supports encryption/decryption switching, one-click copying, input/output interchange, and retains conversion history for easy review and reuse.

Key Forging: Forges random passwords according to length and character set (uppercase, lowercase, numbers, symbols), or generates easy-to-remember passphrases; built-in strength testing and entropy reference help you assess password reliability.

Hash Fingerprint: Locally calculates MD5, SHA-1, SHA-256, SHA-512, etc.; supports comparison of two digests/texts for quick consistency verification.

Pulse Duel: Interactive training with timed ciphertext reading and plaintext selection. Multiple difficulty levels, life points, and a scoring system make cryptography learning more rhythmic.

Local Vault: Securely store encrypted notes locally, with the option to attach a SHA-256 fingerprint; the About page clearly explains the application's capabilities and privacy principles.
