Hash Calculator

Generate SHA-1, SHA-256 or SHA-512 hashes for text.

Your data is processed in your browser, never sent to a server

MD5 is not supported for security reasons. SHA-256 is recommended.

Hash output

Generate MD5, SHA-1 and SHA-256 hashes from your text or password for free, right in your browser. Useful for file integrity checks, password digests and developer testing. Everything runs on your device; the text you enter is never sent to a server.

How it works

Type or paste the text you want to hash into the area above.
Choose the algorithm (MD5, SHA-1, SHA-256).
Copy the resulting hash value.

Frequently asked questions

Is generating a hash free?

Yes, the hash generator is completely free and requires no sign-up.

Is my text sent to a server?

No, the hash is computed entirely in your browser and the text is never sent anywhere.

Which algorithms are available?

Common hash algorithms such as MD5, SHA-1 and SHA-256 are supported.

Can a hash be reversed?

No, a hash is one-way; the same input always gives the same output, but the input cannot be recovered from the output.
