Frequently Asked Questions
What is an MD5 hash used for?
MD5 is used for file integrity verification and checksums. It is NOT suitable for password hashing or security-sensitive applications due to known collision vulnerabilities.
What is SHA-256 used for?
SHA-256 is used in digital signatures, SSL/TLS certificates, file integrity checks, and blockchain proof-of-work. It is considered cryptographically secure.
Should I use MD5 or SHA-256 for passwords?
Neither — use bcrypt, Argon2, or PBKDF2 for password hashing. These are specifically designed to be slow and resistant to brute-force attacks.
Can I hash a file with this tool?
This tool hashes text strings. For file checksums, use a dedicated file hash tool or your OS's built-in tools (`sha256sum` on Linux/Mac, `CertUtil` on Windows).
Is my text data safe to hash here?
Yes — all hashing runs locally in your browser. Nothing is transmitted to any server.
Is this Hash Generator free?
Yes, the Hash Generator is 100% free with no hidden charges or premium subscriptions.
Is my data safe?
Absolutely. All processing happens locally in your browser. We never see, store, or share your data.
Do I need to sign up?
No registration or account creation is required to use any of our tools.
Does it work on mobile?
Yes, our tools are fully responsive and work perfectly on smartphones, tablets, and desktops.
Can I use it offline?
Once the page is loaded, most functions work offline since they run in your browser's local environment.
