What is a hash generator?

A hash generator converts text or file data into a fixed-length hash value. This tool supports SHA-1, SHA-256, SHA-384, and SHA-512.

Is this hash generator free?

Yes. The hash generator is free to use and runs entirely in your browser. Your text and files are not uploaded to a server.

Should I use SHA-1 for new applications?

No. SHA-1 is included for legacy compatibility, but it has collision-resistance weaknesses. Use SHA-256 or SHA-512 for new cryptographic applications.

Can I hash a file online?

Yes. Select a file in the tool to generate its SHA-1, SHA-256, SHA-384, or SHA-512 hash locally in your browser.

Security note: SHA-1 produces a 160-bit digest but has practical collision-resistance weaknesses. Use it only for legacy compatibility; prefer SHA-256 or SHA-512 for new cryptographic applications, signatures, and integrity checks.
