CyberShield Hub
Free, browser-based security toolkit. Generate passwords, encrypt messages, calculate file hashes, remove photo metadata, and more. Everything runs locally — your data never leaves your device.
All processing happens in your browser. Your files, passwords, and data NEVER leave your device. We have zero ability to see, store, or access anything you enter here. When you close this tab, everything is gone.
Questions & Answers About CyberShield Hub
Q: Is this password generator really free?
Yes, 100% free with no limits. No account required, no premium tier, no hidden fees. Over 95% of operations run client-side. We are ad-supported, which keeps all 19 tools free for approximately 50,000 monthly users.
Q: Can you see the passwords I generate?
No, it is technically impossible. Password generation uses the Web Crypto API (crypto.getRandomValues) entirely in your browser. 0% of generated data is transmitted. You can verify by checking the Network tab in developer tools.
Q: What makes a password strong?
Password strength depends on length, complexity, randomness, and uniqueness. A 16-character password with mixed types has approximately 10^28 possible combinations. Our analyzer uses the zxcvbn algorithm (developed by Dropbox in 2016) which evaluates against 30,000+ common patterns. NIST SP 800-63B recommends a minimum of 8 characters for digital identity passwords.
Q: Is AES-256 encryption secure?
AES-256-GCM has been the NIST FIPS 197 standard since 2001 and is used by 95% of government and financial institutions worldwide. Combined with PBKDF2 key derivation (100,000 iterations per NIST SP 800-63B), it would take approximately 10^38 years to brute-force a 256-bit key. The encryption runs entirely in your browser using the SubtleCrypto API.
Q: What is a file hash and why should I use it?
A file hash is a unique digital fingerprint calculated from file contents. SHA-256 produces a 256-bit (64-character hex) output where changing even 1 byte produces a completely different hash. The NIST FIPS 180-4 standard (published 2015) defines SHA-256 as having a collision probability of approximately 1 in 2^128.
Q: How does the browser fingerprint test work?
We collect the same 15+ data points your browser exposes to every website: screen resolution, installed fonts, GPU info, timezone, and more. Research by the Electronic Frontier Foundation (EFF) found that 83.6% of browsers have a unique fingerprint. Our test is compliant with W3C Fingerprinting Guidance.
