Free SHA-512 Hash Generator

Compute the SHA-512 hash of any text or file, instantly and entirely in your browser.

SHA-512 a file

Hash any file locally — nothing is uploaded, it never leaves your browser.

How to generate a SHA-512 hash

  1. 1

    Enter your text

    Type or paste the text you want to hash into the input box.

  2. 2

    Read the hash

    The SHA-512 hash updates automatically, computed locally with your browser's Web Crypto API.

  3. 3

    Copy the result

    Click "Copy hash" to grab the 128-character hex value for your code, config, or checksum file.

Example use cases

1

Verifying file integrity

Compare a downloaded file's SHA-512 hash against a published checksum to confirm it wasn't corrupted or tampered with.

2

High-assurance fingerprinting

Generate a larger digest for archival records or systems that specify SHA-512 over SHA-256.

3

Password & key derivation prep

Compute a SHA-512 digest as a building block in HMAC or key-derivation workflows that call for it.

Frequently asked questions

What is SHA-512?

SHA-512 is part of the SHA-2 family and turns any input into a fixed 512-bit (128 hex character) fingerprint. It offers a larger digest than SHA-256 and is used where a bigger security margin is preferred.

Is SHA-512 more secure than SHA-256?

Both are currently considered cryptographically strong. SHA-512 has a larger output and can be faster on 64-bit hardware, but SHA-256 remains the more common default for most integrity and signing use cases.

Is my data uploaded anywhere?

No. Hashing happens locally in your browser using the Web Crypto API — nothing you type or upload is sent to a server.

Can I hash a whole file, not just text?

Yes — use the "SHA-512 a file" section further down the page to hash any file directly in your browser.
