How to generate SHA-512 hashes

Generate the SHA-512 hash of any text instantly: type or paste text and the SHA-512 digest appears as you type, in lowercase hex, uppercase hex or Base64.

  1. Type or paste your text into the box above.
  2. The SHA-512 hash appears right away: the SHA-512 of hello is 9b71d224bd62f3785d96d46ad3ea3d73319bfbc2890caadae2dff72519673ca72323c3d99ba5c11d7c7acc6e14b8c5da0c4663475c2e5c3adef46f73bcdec043.
  3. Copy the hash, or switch between 17 algorithms and three output formats.

Is SHA-512 secure?

SHA-512 is secure. For passwords, use a slow password hash such as bcrypt or Argon2 instead of any plain hash.

What is SHA-512?

SHA-512 produces a 512-bit hash, shown as 128 hex characters. It is often faster than SHA-256 on 64-bit processors.

Frequently asked questions

Can SHA-512 hashes be reversed?

No. A hash is a one-way function: it can't be turned back into the text. Short, common inputs can still be found in lookup tables, which is why a plain hash must never store passwords.

Why does changing one letter change the whole hash?

Hash functions are designed so that any change to the input, even one bit, produces a completely different result. That makes them good for detecting changes.

Does the text encoding matter?

Yes. The hash is computed from the UTF-8 bytes of the text. Other tools that use a different encoding or add a line break at the end will give a different hash.
