Formula

SHA-512(text) = 512-bit digest, written as 128 hex digits

How the sha-512 hash works

  1. Step oneType or paste the text into the box.
  2. Step twoThe SHA-512 hash appears under it and changes on every key press.
  3. Step threeCopy the hash. The same text always gives exactly the same hash; a change of even one character gives a completely different one.

What this tool does not do

  • A hash cannot be turned back into the text, and this tool does not try to.
  • It is not a password storing method, because it is fast.
  • It hashes the UTF-8 bytes of the text; another text encoding gives another hash.

Frequently asked questions

What is SHA-512?

SHA-512 belongs to the SHA-2 family (FIPS 180-4). It gives a 512-bit value, written as 128 hexadecimal characters.

Is SHA-512 safe to use?

Yes, for hashing data: no practical attack on SHA-512 is known. It is a fast hash, so on its own it is not a good way to store passwords; use a slow, salted password method for that.

Is my text sent anywhere?

No. The hash is worked out inside this page, so the text is not uploaded or saved.
