How to generate a hash
Paste your text
Anything - a password to verify, file contents, a message.
Read all four hashes
MD5, SHA-1, SHA-256 and SHA-512 are computed live side by side.
Copy the one you need
Each hash row has its own copy button.
Hashing questions, answered
Is my text sent anywhere?
No - and for hashing that is essential. Passwords and secrets are hashed by your own browser; nothing touches a server.
Which hash should I use?
SHA-256 is the sensible default for integrity checks and fingerprints. MD5 and SHA-1 are cryptographically broken - fine for checksums against accidental corruption, never for security.
Why does the same text always give the same hash?
That is the point: a hash is a deterministic fingerprint. Change one character and the hash changes completely.
Can I get the original text back from a hash?
No. Hashes are one-way by design. The only 'reversal' is guessing inputs until one matches - which is why long random passwords matter.
