FAQ
Frequently asked questions
Can a hash be reversed to get the original text?
No. Hash functions are one-way: the only way to “reverse” one is to guess inputs until one matches, which is why short or common inputs can be looked up in precomputed tables. Never use a plain hash to store passwords — use bcrypt, scrypt or Argon2.
Why does the same input always give the same hash?
Hash functions are deterministic. Changing a single character produces a completely different digest (the avalanche effect), which makes hashes ideal for checksums, cache keys and integrity checks.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you type, paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
