Frequently Asked Questions

What is a hash used for?

Hashes verify data integrity, store passwords securely, and create digital fingerprints of files or text.

Is MD5 secure for passwords?

No — MD5 is considered cryptographically broken and should not be used for password storage. Use SHA-256 or bcrypt instead.

Are the same input always produce the same hash?

Yes — hash functions are deterministic. The same input always produces the same output hash.

Is my text sent to a server?

No — all hashing happens locally in your browser. Your text is never transmitted or stored.
