Hash Generator

Generate SHA-256, SHA-384 or SHA-512 hashes for text or files, then copy, download or compare the checksum locally in your browser.

Text to hashWhitespace, punctuation and line breaks are included exactly as entered.

How to use Hash Generator

1Choose Text or File, then enter the exact text or select the file you want to hash.
2Choose SHA-256, SHA-384 or SHA-512. Optionally paste an expected checksum to verify.
3Generate the digest, then copy, download or share the hash result.

Useful tips

•For text, spaces, punctuation and line breaks all change the resulting hash.
•When verifying a download, use the same algorithm as the checksum published by the file provider.
•A matching checksum shows the bytes produced the same digest; it does not prove who originally created the file.

Frequently asked questions

Which hash algorithms are supported?

SHA-256, SHA-384 and SHA-512 using the browser Web Crypto API.

Can I verify a file checksum?

Yes. Choose File, select the downloaded file, use the same SHA algorithm, and paste the expected hexadecimal checksum. Wid9et reports whether it matches.

Are my text or files uploaded?

No. Hashing runs locally in your browser and Wid9et does not upload or store the source data or generated digest.
