How to generate a SHA-512 hash

  1. Stay on the Text tab and type or paste content — the SHA-512 updates live.
  2. Or switch to File and drop in a file to hash its exact bytes.
  3. Toggle Uppercase output if you need capitals, then copy the digest.

SHA-512: the largest of the SHA-2 standards

SHA-512 belongs to the same SHA-2 family as SHA-256 but produces a 512-bit, 128-character hexadecimal digest — twice the length. Like SHA-256 it is a current, recommended standard with no known practical collision attacks, so it is fully suitable for security. The wider output gives a larger security margin and, on 64-bit processors, SHA-512 is often computed faster than SHA-256 because its internal operations are built around 64-bit words. That combination makes it a common choice for high-assurance file integrity, long-term archival checksums, hashing large software distributions, and as the underlying function in password-hashing and key-derivation schemes that want extra headroom. In everyday use the practical difference between SHA-256 and SHA-512 is small; pick SHA-512 when a specification asks for it, when you are on 64-bit hardware and want the speed, or when you simply prefer a longer digest. This tool computes SHA-512 with the browser's native, audited Web Crypto API on your device, so your text and files never leave your device, with no upload, watermark, or signup.

Want the more compact modern default instead? Use SHA-256. Matching an older checksum? See SHA-1 or MD5, though neither is safe for security. To generate all four digests together, use the full hash generator.

FAQ

Is SHA-512 more secure than SHA-256?

Both are current, secure SHA-2 standards with no practical attacks. SHA-512 has a larger 512-bit output and a wider security margin, but for most purposes SHA-256 is equally safe; choose SHA-512 when a spec requires it or you want the extra headroom.

Is SHA-512 slower than SHA-256?

Not necessarily. On 64-bit processors SHA-512 is often faster because it operates on 64-bit words, despite producing a longer digest.

When should I pick SHA-512 over SHA-256?

Use it when a standard or system mandates it, when you are hashing on 64-bit hardware and want the speed, or when you prefer the larger digest for high-assurance integrity checks.

Is my text or file uploaded?

No. All hashing happens locally in your browser using the Web Crypto API. Nothing is sent to any server.
