Frequently asked questions
What is hashing?
A one-way function that turns any input into a fixed-length fingerprint — the same input always gives the same hash.
MD5 vs SHA-256 — which should I use?
SHA-256 for security (checksums, integrity). MD5 is fast but cryptographically broken — fine for non-security checks.
Is my text uploaded anywhere?
No — all hashing runs locally in your browser.
Is the hash generator free?
Yes — unlimited, no signup.
